This is CURRENT LIMITING SINGLE CHANNEL DRIVER. Previous Datasheet Index Next Data Sheet Data Sheet No. PD-6.017D IR2125 CURRENT LIMITING SINGLE CHANNEL DRIVER Features n Floating channel designed for bootstrap operation Fully operational to +500V Tolerant to negative transient voltage dV, dt immune n Gate drive supply range from 12 to 18V n Undervoltage lockout n Current detection and limiting loop to limit driven power transistor current n Error lead indicates fault conditions and programs shutdown time n Output in phase with input Product Summary VOFFSET IO+, VOUT VCSth ton, off (typ.) 500V max. 1A , 2A 12 - 18V 230 mV 150 & 150 ns 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. T.
