IR2121
Features Product Summary - Gate drive supply range from 12 to 18V - Undervoltage lockout - Current detection and limiting loop to limit driven power transistor current - Error lead indicates fault conditions and programs shutdown time - Output in phase with input - 2.5V, 5V and 15V input logic patible - Also available LEAD-FREE Description VOFFSET IO+/VOUT VCSth ton/off (typ.) 5V max. 1A / 2A 12 - 18V 230 m V 150 & 150 ns The IR2121 is a high speed power MOSFET and Package IGBT driver with over-current limiting protection cir- cuitry. Latch immune CMOS technology enables rug- gedized monolithic construction. Logic inputs are patible with standard CMOS or LSTTL outputs, down to 2.5V logic. The output driver features a high pulse current buffer stage designed for mini- mum cross-conduction. The protection circuitry de- tects over-current in the driven power transistor and limits the gate drive voltage. Cycle-by-cycle shutdown is programmed by an external capacitor...
