The IRS21091SPBF is a high voltage high speed power MOSFET and IGBT Half-bridge 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 3.3V logic. The output driver features 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 600V.
Floating channel designed for bootstrap operation
Tolerant to negative transient voltage (dV/dt immune)
Under-voltage lockout for both channels
3.3, 5 and 15V 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 ±5V offset
Internal 500ns dead-time and programmable up to 5μs with one external RDT resistor
