PD-60024D IR2125Z CURRENT LIMITING SINGLE CHANNEL DRIVER Features n Floating channel designed for bootstrap operation Fully operational to +400V 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 pro grams shutdown time n Output in phase with input Description The IR2125Z is a high voltage, high speed power MOSFET and IGBT driver with over-current limiting protection circuitry. Proprietary GVIC and latch immune CMOS technologies enable ruggedized minilithic consturction. Logic inputs are compatible with standard CMOS or LSTTL outputs. the ouput driver features a high pulse current buffer stage designed for minimum driver cross-conduction. Product Summary VOFFSET IO+/VOUT VCSth ton/off (typ.) 400V max. 1A / 2A 12 - 18V 230mV 150ns & 150ns 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 400 volts. 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. Symbol VB VS VHO V CC V ERR V CS VIN dVs/dt PD RqJA TJ TS TL Min. Max.
