Fault conditions can quickly put stress on power sources and also on the loads themselves. Without a protective device to interrupt power during fault conditions, the supply can be overloaded or a load can overheat. The LTC1153 is a high-side MOSFET switch controller device with built-in circuit breaker, which turns off the MOSFET switch in the event of a fault. There is a built-in automatic reset, along with an input for thermal shutdown. The trip delay and reset times are fully adjustable. Because of its low (20 μA max) standby current, the LTC1153 can also be used in battery-powered equipment to protect the battery without reducing battery life. The switch can also be controlled with logic input. A status indicator reports fault conditions to a processor.
