The LTC1153 electronic circuit breaker drives a low cost N-channel MOSFET to interrupt power to a sensitive electronic load in the event of an over-current condition.The breaker remains tripped for a period of time set by an external timing capacitor and then is automatically reset.This cycle continues until the over-current condition is removed, protecting both the sensitive load and the MOSFET switch.

The trip current, trip delay time and auto-reset period are programmable over a wide range to accommodate a variety of load impedances. An active high shutdown input of LTC1153 is also provided and interfaces directly to a PTC thermistor for thermal circuit breaking. An open-drain output is provided to report breaker status to the mP.
