DESCRIPTION
The BC910 is a 3A Li-Ion battery charger. It utilizes a 500 KHz 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 BC910 includes complete charge termination circuitry, automatic recharge and a ±1% 4.2V 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 BC910 is available in a DFN3*3_10 package
