IR2122(S) is a high voltage, high-speed power MOSFET and IGBT driver with a floating channel design for bootstrap operation. It is fully operational up to +600V, tolerant to negative transient voltage, and immune to dV/dt. It has a gate drive supply range from 10 to 20V, undervoltage lockout, and compatibility with 3.3V, 5V, and 15V input logic. It also features an FAULT lead to indicate shutdown and an output out of phase with input.
The International Rectifier IR2122(S) is a high voltage, high speed power MOSFET and IGBT driver designed for applications requiring robust performance. Utilizing proprietary HVIC and latch immune CMOS technologies, the device offers ruggedized monolithic construction suitable for driving N-channel power MOSFETs or IGBTs in both high side and low side configurations up to 600 volts.
Key features include a floating channel designed for bootstrap operation, tolerance to negative transient voltages, and immunity to dV/dt. The driver supports gate drive supply ranges from 10 to 20V and includes undervoltage lockout protection. A dedicated FAULT lead indicates when an over-current shutdown has occurred, providing essential system monitoring.
