IR2121PBF

Data Sheet No. PD60018-M IR2121 & (PbF) CURRENT LIMITING LOW SIDE DRIVER Features Gate drive supply range from 12 to 18V Undervoltage lockout Current detection and limiting loop to limit driven Error lead indicates fault conditions and programs Output in phase with input 2.5V, 5V and 15V input logic compatible Also available LEAD-FREE shutdown time power transistor current Product Summary VOFFSET IO+/VOUT VCSth ton/off (typ.) 5V max. 1A / 2A 12 - 18V 230 mV 150 & 150 ns Description The IR2121 is a high speed power MOSFET and Package IGBT driver with over-current limiting protection circuitry. Latch immune CMOS technology enables ruggedized monolithic construction. Logic inputs are compatible with standard CMOS or LSTTL outputs, down to 2.5V logic . The output driver features a high pulse current buf fer stage designed for minimum cross-conduction. The protection circuitry detects over-current in the driven power transistor and limits the gate drive voltage. Cycle-by-cycle shut8-Lead PDIP down is programmed by an external capacitor which directly controls the time interval between detection of the over-current limiting condition and latched shutdown. The output can be used to drive an N-channel power MOSFET or IGBT in the low side configuration.
