ECB01913 Datasheet PDF - E-CMOS Corporation

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
