详细说明： Wuxi Zcc-china Microne Electrionic show the new product for General Description 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 ra nge of handheld applications. The ZCC6688 includes complete charge termination circuitry, automatic recharge and a ±1% 4.2V / 8.4V / 12.6V float voltage. Battery charge current, charge timeout and end-ofcharge 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. Features Input voltage range 4V~20V 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 ESOP8 RoHS Compliant and 100% Lead (Pb)-Free
