About This Product

■Summary

The MP2664 is a highly integrated single-cell Li-Ion/Li-Polymer battery charger with system power path management for space-constrained portable applications. The MP2664 uses input power from the AC adapter or USB port to supply the system load and charge the battery independently. The charger features constant current precharge, constant current fast charging (CC) and constant voltage (CV) regulation, charge termination, and automatic recharging. The power path management feature ensures continuous power to the system by automatically selecting the input, battery, or both to power the system. This power stage has a low dropout regulator from the input to the system and a 100mΩ switch from the battery to the system. Power path management separates the charging current from the system load, allowing for graceful charging termination and keeping the battery fully charged. The MP2664 provides short circuit protection (SCP) for the system by limiting current from the input to the system and from the battery to the system. This feature is especially important to prevent damage to lithium-ion batteries due to excessively high currents. On-chip battery undervoltage lockout (UVLO) prevents over-discharging of lithium-ion batteries by interrupting the path between the battery and the system when the battery voltage falls below a programmable battery UVLO threshold. An integrated I2C control interface allows the MP2664 to program charging parameters such as input current limit, input minimum voltage regulation, charging current, battery regulation voltage, safety timer, and battery UVLO. The MP2664 is available in a QFN-10 (2mm x 2mm) package.

■Features and benefits

・Fully autonomous charger for single-cell Li-ion/Li-Polymer batteries - Complete power path management to simultaneously power the system and charge the battery ・Charging voltage accuracy of ±0.5% ・Maximum voltage for 13V input source ・I2C interface for charging parameter setting and status reporting ・Fully integrated power switch, no external anti-reverse diode required
