MP2615C

2.1A, 1- or 2-Cell Li-ion Battery Charger with 25mohm Rsns

Datasheet

Description

The MP2615C is a high-efficiency, switch-mode battery charger suitable for single-cell or dual-cell 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.

Evaluation Tools

EV2615C-Q-00A Evaluation Kit 2A, 1- or 2-Cell Li-Ion Battery Charger Evaluation Board

The EV2615C-Q-00A is an evaluation board for the MP2615C, a switching charger for 1- or 2-cell Li-ion or Li-polymer batteries. The MP2615C provides built-in power MOSFETs. The device can achieve up to 2A of charge current, which can be configured by an accurate sense resistor across the whole input range.

The MP2615C regulates the charge current and full battery voltage using two control loops for high-accuracy constant current (CC) charge and constant voltage (CV) charge.

Constant-off-time (COT) control allows a 99% duty cycle to be achieved when the battery voltage is close to the input voltage. This keeps the charge current at a relatively high level.

The battery temperature and charging status are always monitored for each condition. Two output pins 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.
