TS1107/10 Data Sheet Electronic Circuit Breaker: High Side Current Sense Amplifier with KEY FEATURES Current Limiter Comparator and FET Control (TS1110 only) Circuit Breaker with Latching Load The TS1110 Electronic Circuit Breaker uses a bidirectional current-sense amplifier for Disconnect current limit detection to disconnect the load by use of an external P-channel MOSFET. Internal Latching Current Limiter An internal Current Limit Comparator with an adjustable threshold provides a latch capa- Comparator with CLATCH Reset ble output to signal when a fault condition has occurred. Once the Current Limit Compa- Programmable Current Limit rators output is latched the internal FET control is enabled which drives the gate of the COUT Output Signals Fault Condition external P-channel MOSFET, disconnecting the load from the power supply. Once the Low Supply Current fault condition is removed, the system may be reset by strobing or pulling the latch ena- Current Sense Amplifier: 0.68 A ble pin, CLATCH, low. The Circuit Breaker system delay of the TS1110 is typically 428 TS1110 I : 1.16 A s. The Current Limiter system delay of the TS1107 and TS1110 is typically 670 s.
