Li + LINEAR Charger With System Power Path Management, 1.5A MAX Charge Current
Session Titefor popup
MP2607 is a highly-integrated single-cell Li-Ion/Li-Polymer battery charger with system power path management function. It takes input from either AC adapter or USB port to supply the system and charge the battery independently. The charger section features trickle charge, high-accuracy constant current (CC) and constant voltage (CV) regulation, charge termination and charge status.
The system power path management function ensures continuous supply to the system by automatically selecting the input, the battery or both to power the system. This section features a low drop-out regulator from input to system, and a 50mO switch from battery to system. Power path management separates charging current from system load, which allows proper charge termination and keeps battery stay fully-charged. It also allows instantaneous power up of system with a deeply discharged battery.
MP2607 is available in 14pin 3mm*4mm QFN package.

EV2607DL-00A Evaluation Kit Linear Li-Ion Battery Charger With System Power Path Management Evaluation Board
The EV2607DL-00A is an evaluation board for the MP2607, a linear, high?performance single cell Li-Ion battery charger integrated system power path management. It takes power input from either AC adapter or USB port to power the system and charge the battery independently.
The charger section features trickle charge, constant current (CC) and constant voltage (CV) charging modes with programmable charge current, charging termination and charge status.
The system power path management function ensures continuous supply to the system. It features a low drop-out regulator from input to system and a switch from battery to system. If the input is valid, the power path management separates charging function and powering system load. If the input is removed, the system load will be powered by battery.
