Data Sheet PD No. 60255 revA Not recommended for new design: please use IRS21850 IRS21851SPbF SINGLE HIGH SIDE DRIVER IC Features Product Summary Gate drive supply range from 10 V to 20 V Undervoltage lockout for V and V BS CC V 600 V max. OFFSET 3.3 V and 5 V input logic compatible Tolerant to negative transient voltage I +/- 4 A / 4 A O Matched propagation delays for all channels RoHS compliant V 10 V - 20 V OUT Description t (typ.) 160 ns & 160 ns on/off The IRS21851 is a high voltage, high speed power MOSFET and IGBT single high-side driver with propa- Package gation delay matched output channels. Proprietary HVIC and latch immune CMOS technologies enable ruggedized monolithic construction. The floating logic input is compatible with standard CMOS or LSTTL output, down to 3.3 V logic and can be operated up to 600 V above the ground. The output driver features a high pulse current buffer stage designed for mini- mum driver cross-conduction. The floating channel can be used to drive an N-channel power MOSFET 8-Lead SOIC IRS21851 or IGBT in the high- side configuration, which oper- ates up to 600 V.
