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
16-Lead SOIC
8-Lead PDIP
logic. The output driver features a high pulse current
(Wide Body)
buffer stage designed for minimum driver cross-
conduction. The protection circuitry detects over-current in the driven power transistor and limits the gate drive volt-
age. 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.
