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 capable output to signal when a fault condition has occurred. Once the Current Limit Comparator’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 enable 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.
