MP2615B is a monolithic switching charger for a 1 cell lithium-Ion or lithium-polymer battery packed with built-in power MOSFETs. It’s able to achieve up to 2A charge current which can be programmed via an accurate sense resistor over the whole input range. MP2615B regulates the charge current and full battery voltage using two control loops to realize high accuracy constant current (CC) charge and constant voltage (CV) charge. Thanks to the constant-off-time (COT) mode control, 99% duty cycle can be achieved when battery voltage is close to the input voltage to keep the charge current always at a relative high level. Battery temperature and charging status are always monitored for each condition. Two status monitor output pins are provided to indicate the battery charging status and input power status. It features internal reverse blocking protection. Available in QFN-16 (3mmx3mm) package. Applications include smart, portable hand-held solutions and portable media players.
