Ir2110 Mosfet Driver Circuit Diagram Schematics
This IC can be used as both Mosfet driver and IGBT driver. These IC’s are commonly used in half-bridge circuits for switching Mosfets. You can use this IC in high-frequency applications due to its matched propagation delays. It is used in high voltage applications for switching discrete power Mosfets ON and OFF using low voltage input.
How to use IR2112 MOSFET/IGBT Driver?
The connection diagram of this IC 12R2112 are shown in the figure below. HIN and LIN are the input signals for high and low driver side. They connect to some microcontroller or a voltage supply through a switch and is provided with an input signal of range 4 to 5V. It has a shutdown pin which is provided to protect the circuit in case of over voltages or current by connecting this pin to +5V. It will shut down the circuit.
Bootstrap Capacitor
Bto plusdeck2 software. You can see a capacitor between and Vs from the figure below. This is a bootstrap capacitor and its function is to fully operate the high driver side of Mosfet. One end of the bootstrap capacitor is connected to the diode. The doide will charge the capacitor and prevent discharging when is High. For proper switching of the mosfet gate, this capacitor should be charged up between 10 to 20V. After connecting all the input pins, switch ON the power supply.
If you want to drive high side MOSFET, connect HIN to High signal and HO pin will produce HIGH output. To turn-off the high side, apply low signal on HIN pin. Same is the case of LIN pin. When Vs is HIGH, the output at HO will be equal to Vb level, with respect to Vs, When Vs is LOW, the value on HO will be equal to Vs with reference to Vs which means 0 logic.

IR2110 Introduction
In many applications MOSFETs configured as high-side switches and many times, it is configured as high-side and low-side switch. In such applications high-low side MOSFET drivers are used. IR2110 is the most popular high and low side driver IC. The IR2110 is a high voltage, high-speed power MOSFET and IGBT drivers with independent high and low side referenced output channels. Proprietary HVIC and latch immune CMOS technologies enable ruggedized monolithic construction. Logic inputs are compatible with standard CMOS or LSTTL output, down to 3.3V logic. The output drivers feature a high pulse current buffer stage designed for minimum driver cross-conduction. Propagation delays are matched to simplify use in high-frequency applications. The floating channel can be used to drive an N-channel power MOSFET or IGBT in the high side configuration which operates up to 500 or 600 volts.
