1 / 22 page TS1107/10 Data Sheet Electronic Circuit Breaker: High Side Current Sense Amplifier with Current Limiter Comparator and FET Control (TS1110 only) The TS1110 Electronic Circuit Breaker uses a bidirectional current-sense amplifier for current limit detection to disconnect the load by use of an external P-channel MOSFET. An internal Current Limit Comparator with an adjustable threshold provides a latch capa- ble output to signal when a fault condition has occurred. Once the Current Limit Compa- rator’s output is latched the internal FET control is enabled which drives the gate of the external P-channel MOSFET, disconnecting the load from the power supply. Once the fault condition is removed, the system may be reset by strobing or pulling the latch ena- ble pin, CLATCH, low. The Circuit Breaker system delay of the TS1110 is typically 428 µs. The Current Limiter system delay of the TS1107 and TS1110 is typically 670 µs.
