IRS21953SPBF

IRS21953SPBF Features • • • • • • • 2 low side output channels sharing common ground 1 high side output channel CMOS Schmitt trigger inputs with pull down resistor Under voltage lockout on all channels 5 V compatible logic level Inputs Immune to –Vs spike and tolerant to dVs/dt & dVss/dt Shoot through prevention logic HIGH SIDE & DUAL LOW SIDE DRIVER IC Product Summary VOFFSET (low side) VOFFSET (high side) VOUT ton/toff (typ) -600 V (VSS) 600 V (COM) 10 V to 20 V 380 ns/380 ns 0.5 A/0.5 A Descriptions The IRS21953 contains 2 low side outputs sharing common ground and 1 high side output. Low side drivers can tolerate up to -600 V below input signal (VSS: input supply return). High side driver can tolerate up to 600 V above low side ground (COM: low side supply return). The IRS21953 has better propagation delay and thermal characteristics compared to a photo-coupler driver. The logic inputs are compatible with standard CMOS or LSTTL output. Proprietary HVIC and latch-up immune CMOS technologies enable ruggedized monolithic construction.
