1 / 16 page 1 LTC1153 DESCRIPTIO S FEATURE Auto-Reset Electronic Circuit Breaker s Programmable Trip Delay: 15 µs to >100ms s Programmable Trip Current: 1mA to >20A s Programmbale Auto-Reset Time: 1ms to >10 sec. s 4.5V to 18V Supply Range s Drives Low RDS(ON) N-Channel MOSFETs s Status Output Indicates Fault Condition s Thermal Trip with PTC Thermistor s 8 µA IQ in Standby Mode s No External Charge Pump Capacitors s 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.
