MP2615C集成電路（IC）的電池充電器規(guī)格書PDF中文資料

MP2615C屬于集成電路（IC）的電池充電器。由美國芯源系統有限公司制造生產的MP2615C電池充電器電池充電器 PMIC（電源管理集成電路）是元器件級產品系列，用于在電子設備中實現電池充電控制和充電管理功能。這些器件主要根據電池化學及其設計用于的電池數量來分類，可提供電化學電池和超級電容器安全充電所必需的電流或電壓調節(jié)和監(jiān)視功能。

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.
