QC 2.0 compliant Portable Power Bank Single Chip IC

Features

Internally embedded 1A Max. charge mode, charging current adjustable when under 1A；

OVP function when charge , charge terminated when charge voltage over 6.2V；

Trickling/CC/CV three charging stages , fully charges voltage of 4.22V adjustable 0 V Battery chargeable

Thermo charging protection function, charging current starts to decline from 120 degree Celsius, could lower down to

zero output.

Fixed switching frequency @ 650KHZ in discharge, Power MOSFET driven externally and moderately to reach flexible

application

Internal 0.6V reference Voltage, adjustable output voltage; Internal 0.68V OVP threshold output current adjustable

Meet dual start up modes of button and triggered by EN pin

Constant Output Power function with OCP (Over Current) and SCP (Short Circuit Protection)

Boost function allowed during charge period, indicating LED remains charging status and capacity

boost starts when loading being sense, fall into sleeping mode when loading removed or under 50mA

4 indicating LED controlled to show capacity precisely

Can be defined as a Li- ion battery charger specifically

Direct drive Flashlight LED with max. 50mA without external resistors required

Battery over- charge and over- discharge protection
