最大充电电流3A，开关型多节锂电池降压充电芯片-ZCC6688
|
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.
Features
Input voltage range 4V~10V
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
Optional Battery Temperature Monitoring Before and During Charge Automatic Sleep Mode for
Low-Power
Over Current Protection
Consumption Available in ESOP10
RoHS Compliant and 100% Lead (Pb)-Free
Applications
Portable Media Players
Cellular and Smart mobile phone
PDA/DSC
Handheld Battery-Powered Devices
Handheld Computers
Charging Docks and Cradles
