MP2667GG-0000-P

The MP2667 is a highly integrated, single-cell, Li-ion/Li-polymer battery charger with system power path management for space-limited portable applications. The MP2667 takes input power from either an AC adapter or a USB port to supply the system load and charge the battery simultaneously. The charger function features constant current pre-charge, constant current fast charge (CC) and constant voltage (CV) regulation, charge termination and auto-recharge. The power path management function ensures continuous power to the system by automatically selecting the input, battery or both to power the system. This power stage features a low-dropout regulator from the input to the system and a 100mohm switch from the battery to the system. Power path management separates the charging current from the system load, which allows for proper charge termination and keeps the battery in full-charge mode.

• Compatible with 5V USB power sources
• Programmable input current limit and minimum input voltage regulation thresholds
• ±0.5% charging voltage accuracy
• 13V maximum voltage for the input source
• I2C interface for programming charging parameters and status reporting
• Fully integrated power switches and no external blocking diode required
• Built-in robust charging protection including battery temperature monitoring and programmable timer
• Built-in battery disconnection function for shipping mode
• Thermal Limiting Regulation on the Chip
