Linear Charger IC for Li-ion battery With Ultra-small Package Compatible With Wireless Charging
The XC6810 is a linear charger IC for Li-ion battery with ultra-small package compatible with a wireless charging and contact power supply.
The charging current corresponds to 1mA to 25mA, and it has a current path function that supplies power to the system at the same time as charging.
To realize an ultra-compact 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 communication. Ideal for monitoring and displaying the charging status of various wearable devices with the cradle.
