*Ir2110 Mosfet Driver Circuit Diagram ReplacementWhile designing the UPS circuits, MOSFET were used in the inverter circuits. The MOSFETs were used as High side switches in the circuit. For driving the MOSFET in high side configuration, IR2110 gate driver IC was used. IR2110 is a High –Low side Gate Driver IC which is used with power MOSFET and IGBT. A Gate Driver is a specially designed circuit that is used to drive the Gate of MOSFET or IGBT in High Side Switching application. That means when MOSFET/IGBT is used in High side configuration then a gate driver IC is needed.In this tutorial, some important concepts like the High and Low side Switching of MOSFET, need of Gate Driver circuit and driving methods of High side MOSFETs will be discussed. These concepts will crystal clear the working of MOSFET as a switch and will so justify the use of MOSFET in the inverter circuit as switching component. Components Required – Fig. 1: List of components required for High and Low Side Switching of MOSFETCircuit Connections – When a MOSFET or any transistor is used as a switch, there can be two modes of switching – ii)High side switchingIn both the switching methods, there is only difference of position of the load in the circuit. In low side switching, the source of the MOSFET is directly connected to the ground. The load (shown as resistance RL in the circuit diagram) is placed in between the drain and the power supply. Fig. 2: Prototype of MOSFET connected as Low Side SwitchIn high side switching, only the position of load is changed. In high side configuration, the load is connected between the source of the MOSFET and the ground. Since MOSFET is a voltage controlled device, for providing appropriate voltage drop at the terminals of the MOSFET, some resistors need to be connected at the gate and source of the MOSFET. Fig. 3: Prototype of MOSFET connected as High Side SwitchWhile assembling these circuits, always use a gate to source resistance (Shown as Rgs in the circuit diagram) to avoid any external noise at the gate. This resistance also discharge the parasitic capacitance of the MOSFET. Otherwise, the MOSFET can get damaged as this parasitic capacitor will keep on charging and exceed the limit of the gate to source breakdown voltage. Also, do not exceed the input voltage (drain voltage and gate voltage) of MOSFET greater than its breakdown voltage as it can damage the MOSFET. A low-value resistor (10E to 500E) should be used at the gate of MOSFET. This will solve the problem of ringing (parasitic oscillations) and voltage spike in the MOSFET.How the circuit works – In low side switching, the load resistance is connected at the drain side of the MOSFET. As the MOSFET is a voltage controlled device, so for turning ON the MOSFET, the Gate to Source Voltage (Vgs) must be greater than the Gate to Source Threshold Voltage (Vth). In low side switching, there is no need of a gate driver circuit. In this switching mode as the source is directly connected to the ground so, Source Voltage, Vs = 0 V Considering gate to source threshold voltage, Vth = 4 V So, for turning on the MOSFET, gate to source voltage (Vgs) should be greater than gate to source threshold voltage (Vth). Vgs = Vg – 0 > 4VTherefore for turning ON the MOSFET, the gate voltage should be equal to 4 V. Since the applied voltage is usually 5V, this makes the low side switching process easy to implement without using any external circuitry.Fig. 4: Circuit Diagram of MOSFET as Low Side SwitchIn high side switching, the load is connected at the source side. In this configuration, When a trigger voltage is applied to the gate then MOSFET has a very low drain to source resistance i.e. Rds is very low (from milliohms to ohms depending on the type of MOSFET).Fig. 5: Circuit Diagram of MOSFET as High Side SwitchFor simplicity, the MOSFET can be represented as a resistance (drain to source resistance, Rds). Now, the voltage across the MOSFET becomes dependant on the voltage divider so formed.
Fig. 6: Simplified Circuit Diagram of MOSFET as High Side Switch
The value of Source Voltage (Vs) can be calculated in the above circuit by applying the voltage divider rule. Voltage across Load RL, VL( or Vs) = (Vin * RL)/(Rds + RL)Where input voltage, Vin = 5V (as commonly in circuits)Considering Drain to Source Resistance, Rds = 10 ohmsSince Drain to Source Resistance (Rds) is very low as compared to RL, so it can be ignored in the voltage divider rule. So, VL= Vin = 5V (approx.)So Vs = 5V(approx.)The Gate to Source Voltage should be greater than gate to Source Threshold Voltage. Vgs = Vg – Vs > VthSo, Vg > 8VThe gate voltage should be greater than 8 V to turn on the MOSFET. But the input voltage is only 5V, that means the high side MOSFET cannot be driven by applying the same voltage at the base and drain of MOSFET. So for driving high side MOSFET, some extra circuitry is needed which can drive the gate of the MOSFET higher than the drain voltage. This extra circuitry is called Gate Driver Circuit. There are two common methods for driving the MOSFET in high side switching – 1) Dual power supply – This method is very simple but it needs two power source. In this method, the voltage is applied at drain and gate of MOSFET by separate power supplies. So that higher voltage can be provided at the gate compared to drain of the MOSFET. This way the MOSFET can be turned ON. 2) Using Bootstrap circuit – In this method a single power source is needed, using some capacitor in the circuit. This way double or higher voltage is obtained at the gate terminal compared to the drain of the MOSFET. The capacitor in the circuit is called Bootstrap capacitor as it boost up the gate signal to a higher voltage. So by the help of the bootstrap circuit, the MOSFET can be turned ON in high side switching.For learning more about the Bootstrap circuit, check out the following tutorial – Some manufacturers also provide specially designed ICs (commonly known as gate driver ICs) for driving the high side MOSFET. Depending on the type of IC, the IC can drive only high side or low side or it can drive high as well as low side switching simultaneously. So ICs which can drive both high and low side switching can drive the half bridge circuit, which uses one MOSFET in high side and another one in low side configuration. So for driving an H-bridge circuit (combination of two half bridge), two gate drive ICs each for driving single half-bridge need to be used. Generally, these ICs work on bootstrap technique for driving the high side MOSFET and for low side MOSFET, these simply use a transistor logic. The IR2110 IC is one of the ICs which can drive the high and low side MOSFET simultaneously. So, the Low-side MOSFET can be turned ON without any external circuitry. But for driving the High-side MOSFET some gate driver circuit is must.In the next tutorial, learn about testing the IR2110 IC. It is important to test the IR2110 IC before connecting it as a gate driver. Ir2110 Mosfet Driver Circuit Diagram ChartProject VideoIn the previous tutorial, it was discussed that for driving a MOSFET as high side switch, a gate driver circuit needs to be used. The IR2110 IC is one of the high speed and high voltage gate driver ICs for IGBT and power MOSFET. The IC is having independent low and high side output channel. By using a single IC, a half bridge circuit can be operated in which one MOSFET is in high side configuration and another one is in the low side configuration. For driving the high side MOSFET, this IC uses a bootstrap circuit which otherwise could have to be designed externally. Before using this IC for driving the half or full bridge circuit, it is necessary to test the faultiness of the IC. A faulty IC can give unstable output and may blow up the MOSFET or other components in the circuit. In this tutorial, the method to test the IR2110 IC is discussed. Components Required – 1. DC power supply of 5V and 12V. 3. Microcontroller atmega328The IR2110 IC comes in a 14-pin DIP package. It has the following pin configuration – Fig. 1: List of Components required for IR2110 Gate Driver IC TesterThe IR-2110 has the following pin diagram – Fig. 2: Pin Diagram of IR2110 ICThe IR2110 has the following internal circuitry – Source: www.irf.comIn the internal circuit diagram of IR2110, the low side and high side blocks are separated with a dotted line for simplicity. The upper half circuit works for driving high side MOSFET and lower half is for driving the low side MOSFET.As in accordance to the pin configuration of IR2110, the SD (shutdown) pin is used to shutdown the IC. This pin is active high, so for enabling the IC to work, this pin is connected to the ground. The VDD is the supply voltage for driving the internal circuitry of the IC and it should be in between 3V to 20 V (with reference to Vss) as per the datasheet. The VCC is directly connected to the drain of internal MOSFET of low side driver(as shown in internal circuit diagram of IR2110) and it can be in between 10V to 20V. For testing the IR 2110 IC, 5V is taken as VDD and 12V is taken as VCC. When the input at Lin or Hin pin is high then the IC gives High output at LO or HO pin corresponding to the input supply. When logic input at Lin and Hin are low then a low is obtained at LO and HO pin.A square wave is applied at the Lin and Hin pin with the zero phase difference between them and the wave is generated using a microcontroller. For a good IC when Hin pin is high then it should give high at output otherwise low, same for Lin and LO.For testing the IC, the 5V is taken as VDD and 12V is taken as VCC. The supply voltage for VDD and VCC can be drawn from a battery and then regulated to 5V and 12V level using 7805 and 7812 voltage regulator ICs. For voltage regulation, the anode of the battery should be connected to pin 1 of the voltage regulator ICs and pin 2 should be grounded. The respective voltage outputs then can be drawn from the pin 3 of the regulator ICs. The square wave which has to be applied at the input of Lin and Hin pin is generated by a microcontroller. The controller works on TTL (transistor- transistor logic). So to avoid any synchronization error in between VDD and Hin/Lin input supply, 5V is taken as VDD. So, the VDD pin is connected to 5V while VCC and Vb pins are connected to 12V power source. The SD, Vss, COM and Vs pins are connected to the ground. The square wave can be generated using any microcontroller board. In testing for this IC, the square wave has been generated using Arduino board. The Arduino is the most popular prototyping board and can be easily programmed to generate a perfect square wave. Since the square wave has to be applied at two pins of the IR2110, the Arduino is programmed to output square wave from two of its pins. While assembling the circuit for testing the IR2110 IC, following precautions must be taken care of – 1. Never exceed the input voltage of VDD and VCC above their range as it may damage the IC. Check the input voltage limits from the datasheet of IR2110.2. Always common the ground of 12V and 5V supply.3. If TTL power source is used for Lin and Hin pin then VDD must be taken equal to 5V. This should be done to avoid any undermine state at the output. 4. Apply a clean DC to the IC to avoid any voltage spikes. For this, an electrolyte capacitor in parallel with ceramic capacitor for filtering the input power supply can be used.5. Make proper connections as loose connections can result into abrupt wave at the output. Fig. 4: Prototype of circuit for testing IR2110 MOSFET Gate Driver ICHow the circuit works – From the internal circuit it can be seen that in high side and lows side, there are two MOSFETs at the end followed by a latch (on high side) and an AND gate (on low side).

When the output from SR latch (on high side) is low then a bubble at output convert this to high and this makes the MOSFET Q1 ON and MOSFET Q2 OFF. This gives high output at HO pin. Whenever the SR latch gives low then it turns ON the MOSFET Q2 and turns OFF the MOSFET Q1 and a low is obtained at LO pin.

Autodesk 2018 All Products xForce keygen x86 x64 Is up to date. Similarly, on the low side when the output from AND gate is high then MOSFET Q3 is ON and MOSFET Q4 is OFF. So, high output is obtained at LO pin. In the case of low output from AND gate then LO pin gives low output. The generated square wave from the controller should be applied at the Hin and Lin pins and at the output pins (LO and HO respectively) a square wave of same amplitude and frequency should be obtained. If the exact square wave is not obtained at the LO and HO pins or no square wave is output fromeither pin, then IR2110 in case is faulty. If the IC is heating too fast despite not exceeding input supply voltages beyond limit, then also the IC can be predicted to be faulty. Testing the IR2110 IC – After applying the square waves at Lin and Hin pins, the following voltage waveforms at the Lo and Ho pins were observed on a Cathode Ray Oscilloscope.
