MP3401A is a power bank solution device which is highly integrated with linear charger, LED battery display cell and synchronous boost output. The MP3401A has two operating modes, charge mode and boost mode, to manage the system and battery power based on the state of the input. When input power is present, the MP3401A operates in charge mode. It automatically detects the battery voltage and charges the battery in the three phases: trickle current mode, constant current mode and constant voltage mode. In the absence of input source, MP3401A switches to boost mode automatically when the battery voltage is higher than 3.2V.
Linear charge, synchronous boost output, built- in power MOS for charge and discharge
