Product Overview

The LTC1153CS8#PBF is an auto-reset Electronic Circuit Breaker drives 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.
  • Programmable auto-reset time - 1ms to >10sec
  • Status output indicates fault condition
  • Thermal trip with PTC thermistor
  • 8µA IQ in standby mode
  • No external charge pump capacitors
  • Drives low RDS(ON) N-channel MOSFETs
