IR2112S SOIC-16-300mil Gate Drive IC SMD

The IR2112(S) is a high voltage, high speed power MOSFET and IGBT driver with independent high and low side referenced output channels. Proprietary HVIC and latch immune CMOS technologies enable ruggedized monolithic construction. Logic inputs are compatible with standard CMOS or LSTTL outputs, down to 3.3V logic.

Summary of 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 to 20 V
• Undervoltage lockout for both channels
• 3.3 V logic compatible
• Separate logic supply range from 3.3 V to 20 V
• Logic and power ground +/- 5 V offset
• CMOS Schmitt-triggered inputs with pull-down
• Cycle by cycle edge-triggered shutdown logic
• Matched propagation delay for both channels
• Outputs in phase with inputs
