IO+/- 1A / 2A VOUT 12 - 18V VCSth 230 mV ton/off (typ.) 150 & 150 ns Package Description The IR2125 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 standard CMOS or LSTTL outputs. 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 shut- down. 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.
