製品説明

The MP2631 is a linear, high performance single cell Li-Ion or Li-Polymer battery charger with 10mA LDO and on-chip input polarity reverse protection. By integrating high voltage input protection into the charger IC, the MP2631 can tolerate an input surge up to 28V and input surge down to -16V.

The MP2631 features constant current (CC) and constant voltage (CV) charging modes with programmable charge current (200mA to 1A) reverse current blocking and trickle charge.

The other features include the internally set battery full threshold (10% of the programmed charge current) and auto-recharge.

The OVP circuitry will automatically disconnect both charger and LDO from input when VIN exceeds 7V.

28V, 1A, Li-lon, Linear Battery Charger, with 10mA High Voltage LDO

The MP2631 is a linear, high performance single cell Li-Ion or Li-Polymer battery charger with 10mA LDO. By integrating high voltage input protection into the charger IC, the MP2631 can tolerate an input surge up to 28V. The internal 5V LDO can be used as a system watchdog supply to monitor charge status. The LDO is ON when the input voltage is greater than 3V and less than 7V, and remains ON when the MP2631 is in SHDN mode. When input is higher than 7.0V, the LDO output will be cut off from the input. When input is lower than 5V, the LDO will work in the dropout region. The device features constant current (CC) and constant voltage (CV) charging modes with programmable charge current (200mA to 1A), auto-recharge and trickle charge. MP2631 provides ACOK and charge status indications to the system. The OVP circuitry will automatically disconnect both charger and LDO from input when VIN exceeds 7V. For guaranteed safe operation, the MP2631 limits the die temperature to a preset value when the device is heated up due to limited PCB space. MP2631 is available in 10-pin 3mm x 3mm QFN package.
