MAX8856ETD+T

The MAX8856ETD+T is an USB/AC adapter, Li+ linear battery charger with integrated 50mohm battery switch in 14 pin TDFN package. This device is a 1-cell Li+ battery charge-management IC which operates from either a USB port or AC adapter. It integrates a battery disconnect switch, current-sense circuit, PMOS pass element and thermal-regulation circuitry. It eliminates external reverse-blocking Schottky diode to create a simple and small charging solution. The charging sequence initiates from power-OK indication through pre-qualification, fast-charge, top-off charge and finally charging-complete indication for single-cell Li+ batteries. Charging is controlled using constant current, constant voltage or constant die-temperature (CCCVCTJ) regulation for safe operation in handhelds.
