Product Description

The MP26075 is a linear, high performance, and high efficiency single cell Li-Ion or Li-polymer battery charger for AC adapter input in the plug-in, cradle charger applications. The device will control the AC adapter output voltage against the battery voltage to increases energy efficiency. Additionally, MP26075 can provide very low pre-charge charge current for deep-discharged battery. For guaranteed safe operation, MP26075 controls power up sequencing. It ramps-up AC adapter firstly to limit inrush current when the adapter plug in. Other safety feature includes battery temperature monitoring, charge time-out and fault indications, it also provides input/output over voltage protection and charge status indications. MP26075 is available in QFN 3mm×3mm package.

Single-Cell 1A High Efficiency Cradle Charger Evaluation Board

The EV26075EQ-00A is an evaluation board for the MP26075, a linear, high performance, and high efficiency single cell Li-Ion or Li-polymer battery charger for AC adapter input in the plug-in, cradle charger applications.

For EV26075EQ-00A, the topology for AC-DC conversion is a flyback. HF0100 is the primacy side controller. MP26075 offers the feedback signal through a photo-coupler to control the flyback output voltage against the battery voltage to increases energy efficiency. For guaranteed safe operation, MP26075 controls power up sequencing. It ramps-up AC-Adapter firstly to limit inrush current when Adapter plug in.

The charging current of EV26075DQ-00A is set at 1A, which can be programmed by an external resistor (Rset).
