IRS21814MPBF
Description
The IRS21814MPBF is a high voltage, high speed power MOSFET and IGBT drivers with independent high-
and low-side referenced output channels. Proprietary HVIC and latch immune CMOS technologies enable
ruggedized monolithic construction. The logic input is compatible with standard CMOS or LSTTL output,
down to 3.3 V logic. The output drivers feature a high pulse current buffer stage designed for minimum driver
cross-conduction. The floating channel can be used to drive an N-channel power MOSFET or IGBT in the
high-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.
