RT9554A Datasheet (Richtek) - Battery Output Current Sense Protection

RT9554A, Battery Output Current Sense Protection

The RT9554A is designed for over-current detection.

The current sense amplifier amplifies the voltage across resistor which is connected between CSP and CSN by 200.

The amplified voltage is compared with the voltage of BAT_REF and check whether over-current happens or not.

The RT9554A also provides
