3.8 Battery Charging Block Interface
The MP26021 is a linear, high-performance single cell Li-Ion battery charger. By integrating high
voltage input protection into the charger IC, the MP26021 can Tolerate an input surge up to 28V
The device features constant current (CC) and constant voltage (CV) charging modes with
programmable charge currents(85mA to 1A), programmable battery full threshold, thermal protection,
battery temperature monitoring, reverse current blocking and trickle charge. The device also provides
AC adapter power good and Charge status indications to the system.
MP26021 is available in a 10-pin 3mm x 3mm QFN package.
