Analog Devices Inc. LTC4249 Dual Electronic Circuit Breaker (ECB)

 

Analog Devices Inc. LTC4249 Dual Electronic Circuit Breaker (ECB) provides independent overcurrent protection to a pair of loads. Each channel has a precision enable input, current monitor output, and ready status output. A single resistor configures the ECB threshold. If either channel detects an overcurrent condition, the corresponding breaker disconnects the input from the load. After a circuit breaker event, the open-drain RDY status output of the Analog Devices Inc. LTC4249 pulls low, and the ECB latches off. Toggling the enable input turns the ECB back on after a 1-second cool-off period. The cool-off timer, overtemperature sensor, short-circuit detector, and inrush controller prevents operation outside the circuit breakers' safe operating area.
