XC6810 Datasheet | Torex Semiconductor

DESCRIPTION The XC6810 is a linear charger IC for Li-ion battery with ultra-small package patible with a wireless charging and contact power supply. The charging current corresponds to 1m A to 25m A, and it has a current path function that supplies power to the system at the same time as charging. To realize an ultra-pact system, Battery Over Discharge Protection function, Output Terminal Short Protection function and Battery Voltage Monitor function or Battery Low Voltage Notification function are equipped. And the IC is equipped with a shutdown function and a wake-up function using an external push button to reduce battery consumption when the product is stored or unused. In addition, there is a type that can indicates the charging status by modulating the input current using the CSO. We also have prepared a type that can notify the charging status to the power supply such as a cradle by two-wire munication. Ideal for monitoring and displaying the charging status of various wearable devices with the cradle. - APPLICATIONS - Hearing Aid - Wireless earphones / Headset - Wearable Devices - Wireless charging equipment - Io T devices - Smartcards - FEATURES Input Voltage Range Charge Voltage Charge Current Input Current Limit BAT Sink Current at Shut Down Functions Protection Functions Operating Ambient Temperature Package Environmentally Friendly : 3.5V ~ 28.0V : 3.80V ~ 4.40V (0.05V increments) 1m A ~ 25m A, Set by an external resistor : 110m A : 10n A (TYP.) : Shutdown, Wake-up : Battery Voltage Monitor or Battery Low Voltage Notification : OUT Line Switch Interlocked by UVLO, Charge Enable : Battery Temperature Monitor : Current Path / Input Current Limit : Battery Over Discharge Protection : Output Short Protection : Thermal Control : Reverse Current Prevention : Safty Timer of Charging : UVLO : -40℃ ~ 85℃ : WLP-12-01 (1.17 x 1.57 x 0.33mm) : EU Ro HS pliant, Pb Free - TYPICAL APPLICATON CIRCUIT DC input...
