MA5887中文资料USB Fast Charging Controller数据手册Prolific规格书

描述 Description

With Smartphone and Tab become the mainstream portable mobile devices, the demand for a universal charging (fast charging)” to various mobile devices increase dramatically.
The MA5887 is a USB fast-charging controller which complies with USB Battery Charging Specification (BC) version 1.2, which allows charging device to draw a current similar to using the original wall-charger. Normally, a USB wall-charger provides unified charging mechanism by traditional USB current supply (0.5A) when charging devices through USB ports. With a USB enabled wall-charger
which complies with USB BC, it provides unified charging mechanism by more USB current supply (up to 1.5A) when charging devices through USB ports, so called “fast-charging” mechanism. In another word, MA5887 is a high performance solution for “fast-charging” mechanism and speed up charging time much.
MA5887 embedded automatic charger detection circuit which complies with USB Battery Charging Specification (BC) version 1.2, and Apple/Samsung Tab resistor mode. This feature implies MA5887 supports wide range of Smartphone/Tabs for fast charging and provides design flexibility for system manufactures.
The MA5887 is designed for all charger products with USB interface, which provides the package of SOT23-5 for single USB port support.
