DESCRIPTION
FEATURES
The MP2615A is a high-efficiency, switch mode
battery charger suitable for 1- or 2- cell lithium-
ion or lithium-polymer applications. The
MP2615A is capable of delivering 2 A of charge
current programmable via an accurate sense
resistor over the entire input range.

allows
operation at up to 99% duty cycle when the
battery voltage is close to the input voltage,
ensuring the charge current always remains at
a relatively high level.
The 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. Also, the MP2615A
features internal reverse-blocking protection.
