Description
Packages
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 construction. The logic input is compatible with standard
CMOS or LSTTL outputs, down to 3.3 V. The protection circuity detects over-current in the driven power
transistor and terminates the gate drive voltage. An
8-Lead PDIP
8-Lead SOIC
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 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 V.

Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage parameters are absolute voltages referenced to COM. The thermal resistance and power dissipation ratings are measured
under board mounted and still air conditions.
