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 /12.6V /16.8V 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 ESSOP10 package.
