Description
The lRS2127/lRS2128/lRS21271/lRS21281 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

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