DESCRIPTION
The MP2615C is a high-efficiency, switch-mode
battery charger suitable for single-cell or dualcell
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 also
features internal reverse blocking protection.
The MP2615C is available in a QFN-16
(3mmx3mm) package.
