Features: The Future of Analog IC Technology MP26 15 2A, 1- or 2- Cell Li-ion Battery Cha rger 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 program mable via an accurate sense resistor ov er the entire input range. The MP2615 r egulates the charge current and full ba ttery voltage using two control loops t o achieve high accuracy constant curren t (CC) charge and constant voltage (CV) charge. Constant-off-time (COT) mode c ontrol allows operation up to 99% duty cycle when the battery voltage is close to the input voltage and in order to k eep charge current always at a relative high level. Battery temperature and ch arging status are always monitored duri ng each charging cycle. Two status moni tor output pins are provided to indicat e the battery charging status and input power status. The MP2615 also features internal reverse blocki.

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 lithium-
ion 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 16-
pin QFN package.
