IR2112 High and Low Side Driver IC DIP-14 Package
The
IR2112 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. The output drivers feature a high pulse
current buffer stage designed for minimum driver cross-conduction.
Propagation delays are matched to simplify use in high frequency
applications. The floating channel can be used to drive an N-channel
power MOSFET or IGBT in the high side configuration which operates up to
600 volts.
Features:-
- Floating channel designed for bootstrap operation
- Fully operational to +600V
- Tolerant to negative transient voltage dV/dt immune
- Gate drive supply range from 10 to 20V
- Undervoltage lockout for both channels
- 3.3V logic compatible Separate logic supply range from 3.3V to 20V Logic and power ground ±5V 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
