IR2127 datasheet



The IR2127 / IR2128 / IR21271(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 voltage. An open drain FAULTsignal is provided to 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-channel power MOSFET or IGBT in the high side or low side configuration which operates up to 600 volts.


1. Floating channel designed for bootstrap operation

2. Fully operational to +600V

3. Tolerant to negative transient voltage dV/dt immune

4. Application- specific gate drive range  : Motor Drive: 12 to 20V (IR2127/IR2128)

5. Automotive : 9 to 20V (IR21271)

6. Undervoltage lockout

7. 3.3V, 5V and 15V input logic compatible

8 FAULTlead indicates shutdown has occured

9. Output in phase with input (IR2127/IR21271)

10. Output out of phase with input (IR2128)

11. Avaliable in Lead-Free
