IR2110 Introduction
The IR2110 is a high-voltage, high-speed driver for controlling power MOSFETs and IGBTs, featuring independent high and low side output channels. It utilizes proprietary HVIC and latch-immune CMOS technologies, ensuring robust monolithic construction. The IR2110 is compatible with standard CMOS or LSTTL logic inputs, including 3.3V logic levels.
The driver’s output stage is optimized for high pulse current, minimizing cross-conduction. Matched propagation delays make it ideal for high-frequency applications, and its floating channel can drive an N-channel power MOSFET or IGBT in high-side configurations, supporting voltages up to 500 or 600 volts.
IR2110 Pinout
LO: Low-side gate drive output, connects to the gate of the low-side MOSFET.
COM: Common ground reference for the low-side driver.
VCC: Low-side and logic fixed supply voltage, typically 10V to 20V.
VS: High-side floating supply return, connects to the source of the high-side MOSFET.
VB: High-side floating supply voltage, provides power to the high-side driver.
HO: High-side gate drive output, connects to the gate of the high-side MOSFET.
VDD: Logic power supply, typically 3.3V or 5V.
HIN: Logic input for high-side gate driver, active high.
SD: Shutdown input, active low, disables both high and low-side outputs when active.
LIN: Logic input for low-side gate driver, active high.
VSS: Logic ground.

How to Use IR2110?
1. Connect the logic power supply to VDD and the low voltage supply to VCC, then ground the COM and VSS pins.
2. Connect the high-side and low-side MOSFETs to the HO and LO pins, respectively. Connect the source of the high-side MOSFET to the VS pin, and the VB pin to the high-voltage power supply to drive the high-side MOSFET.
3. Control the high-side and low-side MOSFETs by inputting control signals to the HIN and LIN pins, which will turn them on and off, respectively.
4. To shut down all outputs, pull the SD pin low to enter shutdown mode.
