摘要:该电路保持电源的负载,无论在电源电压瞬间短路或打开,包括低电流过压保护IC ( MAX6495的工作) ,保护负载免受瞬态电压高达72V 。 Maxim > App Notes > Circuit Protection Protection and Isolation Keywords: automotive electronics, overvoltage protection, brownout protection, ride-through capability, MOSFETs Dec 22, 2010 APPLICATION NOTE 4550 Automotive Protection Circuit "Rides Through" Supply-Voltage Interruptions and 72V Transients By:Ronald Moradkhan Abstract:This circuit maintains power to the load regardless of momentary shorts or opens in the supply voltage, and includes a low-current overvoltage-protection IC (MAX6495) that protects the load against transient voltages up to 72V. A similar version of this article appeared in the November 25, 2007 issue of Machine Design magazine. Many applications in automotive electronics require a supply voltage that remains uninterrupt……
