Description

The IR2125(S) is a high voltage, high speed power

MOSFET and IGBT driver with over-current limiting

protection circuitry. Proprietary HVIC and latch im-

mune CMOS technologies enable ruggedized mono-

lithic construction. Logic inputs are compatible with

standard CMOS or LSTTL outputs, down to 2.5V

logic. The output driver features a high pulse current

16-Lead SOIC

(Wide Body)

8-Lead PDIP

buffer stage designed for minimum driver cross-conduction. The protection circuitry detects over-current in the

driven power transistor and limits the gate drive voltage. Cycle by cycle shutdown is programmed by an external

capacitor which directly controls the time interval between detection of the over-current limiting conditions and

latched shutdown. The floating channel can be used to drive an N-channel power MOSFET or IGBT in the high

or low side configuration which operates up to 500 volts.
