Description

The IRS2127/IRS2128/IRS21271/IRS21281 are

high voltage, high speed power MOSFET and IGBT

drivers. Proprietary HVIC and latch immune CMOS

technologies enable ruggedized monolithic construc-

tion. The logic input is compatible with standard

CMOS or LSTTL outputs, down to 3.3 V. The protec-

tion circuity detects over-current in the driven power

transistor and terminates the gate drive voltage. An

open drain FAULT signal is provided to indicate that

an over-current shutdown has occurred. The output

driver features a high pulse current buffer stage designed for minimum cross-conduction. The floating chan-

nel 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 V.
