Description

The IRS21091 is a high voltage, high speed power MOSFET and IGBT driver with dependent 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.

Features

• Floating channel designed for bootstrap operation

• Fully operational to +600 V

• Tolerant to negative transient voltage, dV/dt

immune

• Gate drive supply range from 10 V to 20 V

• Undervoltage lockout for both channels

• 3.3 V, 5 V, and 15 V input logic compatible

• Cross-conduction prevention logic

• Matched propagation delay for both channels

• High-side output in phase with IN input

• Logic and power ground +/- 5 V offset

• Internal 500 ns deadtime, and programmable

up to 5 µs with one external RDT resistor

• Lower di/dt gate driver for better noise immunity

• The dual function DT/SD input turns off both

channels

• RoHS compliant
