转换过程中从闭锁模式打嗝模式短路的电路中的CPU核电源

资料介绍
摘要:本设计笔记显示了如何从闭锁模式转换CPU核心供电,打嗝模式短路时。添加两个廉价的核心控制器的电压比较器,可以使打嗝模式输出短路后重新启动。特色MAX1937/MX1938/MAX1939 CPU内核控制器。

APPLICATION NOTE 1901
Convert a CPU Core Supply from Latchoff Mode to Hiccup Mode
During a Short Circuit


Abstract:This design note shows how to convert a CPU core supply from latchoff mode to hiccup mode during a short circuit.
Adding two inexpensive voltage comparators to core controllers can enable hiccup mode and restart the output after a short
circuit. The MAX1937/MX1938/MAX1939 CPU core controllers are featured.

To prevent excessive power dissipation during output short circuit, the MAX1937/MAX1938/MAX1939 provide a latch off feature
under either short circuit or under-voltage-lockout condition……
