Description

The IRS21851 is a high voltage, high speed power OSFET and IGBT single high-side driver with propagation elay matched output channels. Proprietary VIC and latch immune CMOS technologies enable uggedized monolithic construction. The floating logic nput is compatible with standard CMOS or LSTTL utput, down to 3.3 V logic and can be operated up to 00 V above the ground. The output driver features a igh pulse current buffer stage designed for minimum river cross-conduction. The floating channel an be used to drive an N-channel power MOSFET r IGBT in the high- side configuration, which operates p to 600 V.
