MP2615C is a high-efficiency, switch-mode battery charger suitable for single-cell or dual cell 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 is available in a QFN-16 (3mmx3mm) package. Application include smartphones, portable handheld solutions and portable media players.
