ADP2450ASTZ-3-R7

ADP2450 is a power management IC for circuit breaker application. It integrates one boost shunt controller with power detection, one high efficiency buck regulator, four low offset, low power consumption programmable gain amplifiers (PGAs), one low offset operation amplifier, a fast analogue trip circuit, and an actuator driver. This device is targeted for low voltage circuit breakers, such as the moulded case circuit breaker (MCCB), and current transformer (CT) powered supply applications. The boost output voltage can be upto 36V and integrates a power detection circuit that prevents the circuit from power hiccups. The power detection threshold is programmable with resistors. It is widely used in application such as low voltage circuit breaker, CT powered supply.
