MC3423, Overvoltage Crowbar Sensing Circuit

MC3423 Overvoltage Crowbar Sensing Circuit This overvoltage protection circuit (OVP) protects sensitive electronic circuitry from overvoltage transients or regulator failures when used in conjunction with an external “crowbar” SCR.

The device senses the overvoltage condition and quickly “crowbars” or short circuits the supply, forcing the supply into current limiting or opening the fuse or circuit breaker.

The protection voltage threshold is adjustable and the MC3423 can be programmed for minimu
