IRS4426/IRS4427/IRS4428

Description

The IRS4426/IRS4427/IRS4428 are low voltage, high speed power MOSFET and IGBT drivers. Proprietary

latch immune CMOS technologies enable ruggedized monolithic construction. The logic input is compatible

with standard CMOS or LSTTL output. The output drivers feature a high pulse current buffer stage designed

for minimum driver cross-conduction. Propagation delays between two channels are matched.

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.
