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
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.
