2A, 1- or 2-Cell Li-Ion Battery Charger in 3mmx3mm Package
Learn about our Evaluation Kit
Product Description
The EV2615-Q-00A is an evaluation board for the MP2615, a switching charger for 1- or 2-cell Lithium-ion or Lithium-polymer batteries, packed with built-in power MOSFETs. It is able to achieve up to 2A of charge current, which can be programmed via an accurate current-sense resistor over the whole input range.
The MP2615 regulates the charge current and full battery voltage using two control loops to realize high accuracy constant current (CC) charge and constant voltage (CV) charge. Thanks to the COT mode control, a 99% duty cycle can be achieved when the battery voltage is close to the input voltage to keep the charge current always at a relatively high level.
Battery temperature and charging status are always monitored for each condition. 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.

Parametrics
2A, 1 or 2-Cell Li-ion Battery Charger in QFN 3x3mm package
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.
