描述 Description

    QC 2.0 compliant Portable Power Bank Single Chip IC

 

特性 Features

u Internally embedded 1A Max. charge mode, charging current adjustable when under 1A；
u OVP function when charge , charge terminated when charge voltage over 6.2V；
u Trickling/CC/CV three charging stages , fully charges voltage of 4.22V adjustable 0 V Battery chargeable
u Thermo charging protection function, charging current starts to decline from 120 degree Celsius, could lower down to as
        the bottom.
u Fixed switching frequency @ 650KHZ in discharge, Power MOSFET driven externally and moderately to reach flexible
       application
u Internal 0.6V reference Voltage, adjustable output voltage; Internal 0.68V OVP threshold output  current adjustable
u Meet dual start up modes of button and triggered by EN pin
u Constant Output Power function with OCP (Over Current) and SCP (Short Circuit Protection)
u Boost function allowed during charge period, indicating LED remains charging status and capacity
u boost starts when loading being sense, fall into sleeping mode when loading removed or under 50mA
u 4 indicating LED controlled to show capacity precisely
u Can be defined as a Li- ion battery charger specifically
u Direct drive while light LED as flashlight with max. 50mA without external resistors required
u Battery over- charge and over- discharge protection
u 4KV ESD；
