ZCC6688  
3A Synchronous Buck Li-ion Charger  
General Description  
Features  
Input voltage range 4V~20V  
The ZCC6688 is a 2A 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 float voltage.  
Dynamic input current allocation for maximum  
charging rate  
3.0A Maximum Charge Current  
No External MOSFETs and Blocking Diode  
Required  
Efficiency up to 90%  
Constant-Current/Constant-Voltage Operation  
with Thermal Regulation to Maximize Charge  
Rate Without Risk of Overheating  
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 ESOP8 and package.  
Optional Battery Temperature MonitoringBefore  
and During Charge Automatic Sleep Mode for
