IRS21844PBF Datasheet

Power Driver ICs


The IRS21844PBF 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 technologiesenable ruggedized monolithic construction. The logic input is compatible with standard CMOS or LSTTLoutput,downto3.3V 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. IRS21844PBF 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 and 5 V input logic compatible• Matched propagation delay for both channels• Logic and power ground +/- 5 V offset• Lower di/dt gate driver for better noise immunity• Output source/sink current capability 1.4 A/1.8 A• RoHS compliant
