Description: The IR2127/IR2128/IR21271(S) is a high voltage, highspeed power MOSFET and IGBT driver. Proprietary HVIC and latch immune CMOS technologies enableruggedized 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 voltage. An open drain FAULT signal is providedto indicate that an over-current shutdown has occurred.
The output driver features a high pulse currentbuffer stage designed for minimum cross-conduction.The floating channel can be used to drive an N-channelpower MOSFET or IGBT in the high side or low side configuration which operates up to 600 volts. Documents:
