ZCC6688 3A Synchronous Buck Li-ion Charger，降壓型充電

XX9

General Description

The ZCC6688 is a 3A Li-Ion battery charger. It utilizes a 500KHz synchronous buck converter topology to reduce power dissipation during charging. Low power dissipation, an internal MOSFET allow a physically small charger that can be embedded in a wide range of handheld applications. The ZCC6688 includes complete charge termination circuitry, automatic recharge and a ±1% 4.2V /8.4V float voltage. Battery charge current, charge timeout and end-of- charge indication parameters are set with external components. Additional features include shorted cell detection; temperature qualified charging and overvoltage protection. The ZCC6688 is available in a low profile ESOP10 package.
