Description

The IRS4427 is a low voltage, high speed power MOSFET and IGBT driver. 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.

Recommended Operating Conditions

For proper operation, the device should be used within the recommended conditions. All voltage

parameters are absolute voltages referenced to COM unless otherwise stated in the table. The offset rating

is tested with supply of VCC = 15V.
