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 minimum duration of overvoltage condition

before tripping, thus supplying noise immunity.
The MC3423 is essentially a “two terminal” system, therefore it
can be used with either positive or negative supplies.
