Description

MC3423 . Overvoltage Crowbar. Sensing Circuit. This overvoltage protection circuit (OVP) protects sensitive electronic circuitry from overvoltage transients or MC3423 : Overvoltage Crowbar Sensing Circuit with Adjustable Threshold. Voltage. For complete documentation, see the data sheet. This overvoltage protection OVERVOLTAGE PROTECTOR: THE MC3423 . To fill the need for a low cost, low complexity method or implementing crowbar overvoltage protection which does. MC3423 is originally designed for overvolt crowbar sensing circuit, but it is also applicable in the universal input voltage adaptor because of the similar The MC3423 , U1, is used to sense an overvoltage condition at the output, and will trigger the crowbar SCR,. Q8. The trip voltage is centered at 6.4 V with a
