Description

The IR2121 is a high speed power MOSFET and 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 buffer stage designed for minimum cross-conduction. The protection circuitry detects over-current in the driven power transistor and limits the gate drive voltage.

Features

• Gate drive supply range from 12 to 18V

• Error lead indicates fault conditions and programs shutdown time

• Output in phase with input

• 2.5V, 5V and 15V input logic compatible

• Also available LEAD-FREE
