DESCRIPTIO

EATURE

■

Programmable Trip Delay: 15µs to >100ms

Programmable Trip Current: 1mA to >20A

Programmbale Auto-Reset Time: 1ms to >10 sec.

4.5V to 18V Supply Range

Drives Low R_DS(ON)N-Channel MOSFETs

Status Output Indicates Fault Condition

Thermal Trip with PTC Thermistor

8µA I_Qin Standby Mode

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.

No External Charge Pump Capacitors

Available in 8-Pin SOIC

The trip current, trip delay time and auto-reset period are

programmable over a wide range to accommodate a

varietyofloadimpedances. Anactivehighshutdowninput

isalsoprovidedandinterfacesdirectlytoaPTCthermistor

for thermal circuit breaking. An open-drain output is

provided to report breaker status to the µP.
