IR2122 - International Rectifier

IR2122 CURRENT SENSING SINGLE CHANNEL DRIVER

The IR2122(S) is a high voltage, high speed power MOSFET and IGBT driver. Proprietary HVIC and latch immune CMOS technologies enable ruggedized monolithic construction. The logic input is compatible with standard CMOS or LSTTL outputs, down to 3.3V. The protection circuity detects over-current in the driven power transistor and terminates the gate drive volt.
