MPS MP2615AGQ-Z

锂离子/聚合物2A-40°C ~ 125°C（TJ）

Overview

The MP2615AGQ-Z is a high efficiency switch mode battery charger suitable for 1- or 2- cell lithium-ion or lithium-Polymer applications. The MP2615AGQ-Z is capable of delivering 2A of charge current programmable via an accurate sense resistor over the entire input range. The MP2615AGQ-Z 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 MP2615AGQ-Z also features internal reverse blocking protection.The MP2615AGQ-Z is available in a 3mm × 3mm 16-pin QFN package.
