Data Sheet No. PD60311 IRS21091(S)PbF HALF-BRIDGE DRIVER Features Floating channel designed for bootstrap operation Product Summary Fully operational to +600 V Tolerant to negative transient voltage, dV/dt immune V 600 V max. OFFSET Gate drive supply range from 10 V to 20 V Undervoltage lockout for both channels I +/- 120 mA / 250 mA O 3.3 V, 5 V, and 15 V input logic compatible V 10 V - 20 V Cross-conduction prevention logic OUT Matched propagation delay for both channels t (typ.) 750 ns & 200 ns on/off High-side output in phase with IN input Logic and power ground +/- 5 V offset Deadtime 540 ns Internal 500 ns deadtime, and programmable up to 5 s with one external R resistor DT Lower di/dt gate driver for better noise immunity The dual function DT/SD input turns off both Packages channels RoHS compliant 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 8 Lead PDIP 8 Lead SOIC compatible with standard CMOS or LSTTL output, IRS21091 IRS21091S 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.
