Semiconductor Components Industries, LLC, 2005 March, 2005 Rev. 51 Publication Order Number: MC3423 /DMC3423 Overvoltage CrowbarSensing CircuitThis Overvoltage protection Circuit (OVP) protects sensitiveelectronic circuitry from Overvoltage transients or regulator failureswhen used in conjunction with an external Crowbar SCR. Thedevice senses the Overvoltage condition and quickly crowbars orshort circuits the supply, forcing the supply into current limiting oropening the fuse or Circuit protection voltage threshold is adjustable and the MC3423 canbe programmed for minimum duration of Overvoltage conditionbefore tripping, thus supplying noise MC3423 is essentially a two termi
