Linear Technology LTC1153
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.| Part No. | LTC1153 |
