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.
