Description

The IR2121 is a high speed power MOSFET and

IGBT driver with over-current limiting protection cir-

cuitry. Latch immune CMOS technology enables rug-

gedized 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 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 ex-

ternal capacitor which directly controls the time in-

terval 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.
