DESCRIPTION

The MP2615C is a high-efficiency, switch-mode

battery charger suitable for single-cell or dualcell

Li-ion or Li-polymer applications. The

device is capable of delivering 2.1A of charge

current, which can be configured via an

accurate current-sense resistor across the

entire input range.

The MP2615C regulates the charge current and

full battery voltage using two control loops to

achieve high-accuracy constant current (CC)

charge and constant voltage (CV) charge.

Constant-off-time (COT) control allows the

device to operate up to 99 duty cycle when

the battery voltage is close to the input voltage.

This maintains a relatively high charging

current.

The battery temperature and charging statuses

are always monitored during each charging

cycle. Two status monitor output pins are

provided to indicate the battery charging status

and input power status. The MP2615C also

features internal reverse blocking protection.

The MP2615C is available in a QFN-16

(3mmx3mm) package.
