The Future of Analog IC Technology
MP2615
2A, 1- or 2- Cell Li-ion Battery Charger In 3mm x 3mm Package
DESCRIPTION
The MP2615 is a high efficiency switch mode battery charger suitable for 1- or 2- cell lithiumion or lithium-Polymer applications. The MP2615 is capable of delivering 2A of charge current programmable via an accurate sense resistor over the entire input range.
The MP2615 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) mode control allows operation up to 99% duty cycle when the battery
voltage is close to the input
voltage and in order to keep charge current always at a relative high level.
Battery temperature and charging status 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 MP2615 also features internal reverse blocking protection.
The MP2615 is available in a 3mm × 3mm 16pin QFN package.
