The IRS2108/IRS21084 are high voltage, high speed power MOSFET and IGBT drivers 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 HIN input • Low-side output out of phase with LIN input • Logic and power ground +/- 5 V offset • Internal 540 ns deadtime, and programmable up to 5 µs with one external RDT resistor (IRS21084) • Lower di/dt gate driver for better noise immunity • RoHS compliant
