Product Description

The MP26057 is a linear, high performance single cell Li-Ion or Li-Polymer battery charger with on-chip input polarity reverse protection down to -16V. By integrating high voltage input protection into the charger IC, the MP26057 can tolerate an input surge up to 28V.

The device features constant current (CC) and constant voltage (CV) charging modes with programmable charge currents (200mA to 1A), current blocking and trickle charge. The other features include the programmable battery full threshold, termination and auto-recharge. MP26057 provides charger status indication to drive red and green LEDs (tri-color indication). For guaranteed safe operation, the MP26057 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.
