Available in 8-Pin SOIC
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
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
µP.
The LTC1153 is available in both 8-pin DIP and 8-pin SOIC
packages.
