MP2615
2A, 1- or 2- Cell Li-ion Battery Charger
In 3mm x 3mm Package
DESCRIPTION
FEATURES
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.
4.75V to 18V Operating Input Voltage
Up to 99% Duty Cycle Operation
Up to 2A Programmable Charging Current
±0.75% Full Battery Voltage Accuracy
4.1V/Cell and 4.2V/Cell Selection for Full
Battery Voltage
Full Integrated Power Switches
Internal Loop Compensation
No External Reverse Blocking Diode
Required
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.
Preconditioning for Fully Depleted Battery
Charging Operation Indicator
Programmable Safety Timer
Thermal Shutdown Protection
Cycle-by-Cycle Over Current Protection
Battery Temperature Monitor and Protection
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.
APPLICATIONS
Smart Phones
Portable Hand-held Solutions
Portable Media Players
