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 /12.6V /16.8V float voltage. Battery charge current, charge timeout and end-ofcharge indication parameters are set with external components. Additional features ...
