製品説明

The MP26056  is a linear, high performance single cell Li-Ion or Li-Polymer battery charger with dual programmable  constant current set. By integrating high voltage input protection into the charger IC, the MP26056 can tolerate an input surge up to 28V. The device features constant current (CC) and constant voltage (CV) charging modes, reverse current blocking and trickle charge. Other features include the programmable battery full threshold supporting dual AC/USB input by automatically changing to a lower charge current when the USB is the power supply. The MP26056 also provides ACOK and charge status indications to the system. For guaranteed safe operation, the MP26056 limits the die temperature to a preset value when the device is heated up due to limited PCB space. Other safety features include battery temperature monitoring and programmable timer to prevent prolonged charging a dead battery. MP26056 is available in 10-pin 3mm x 3mm QFN packages.

28V, Li + Single-Cell Battery Charger Evaluation Board

The MP26056 is a linear, high performance single cell Li-Ion or Li-Polymer battery charger with dual programmable constant current set. By integrating high voltage input protection into the charger IC, the MP26056 can tolerate an input surge up to 28V.

The device features constant current (CC), constant voltage (CV) charging modes, and reverse current blocking. The other features include the programmable battery full threshold, supporting dual AC/USB input by automatically change to a lower charge current when USB is the power supply. MP26056 also provides ACOK and charge status indications to the system. MP26056 works as an LDO charger when MOD is LOW or works as a charger with auto-termination and re-charger function when MOD is set HIGH.

For guaranteed safe operation, the MP26056 limits the die temperature to a preset value when the device is heated up due to limited PCB space. Other safety features are battery temperature monitoring, and programmable timer to prevent prolonged charging a dead battery.

MP26056 is available in 10-pin 3mm x 3mm DFN packages.
