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 immune CMOS technologies enable ruggedized monolithic construction. Logic inputs are compatible with
16-Lead SOIC
8-Lead PDIP
standard CMOS or LSTTL outputs, down to 2.5V
(Wide Body)
logic. The output driver features a high pulse current
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.
Typical Connection

Absolute Maximum Ratings
Absolute Maximum Ratings indicate sustained limits beyond which damage to the device may occur. All voltage parameters are absolute voltages referenced to COM. The Thermal Resistance and Power Dissipation ratings are measured
under board mounted and still air conditions.
