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
●• 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 compatible
●• Also available LEAD-FREE
