MP2615C
2.1A, 1-Cell or 2-Cell Li-Ion Battery Charger in (3mmx3mm) Package
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.
