XC6808BND28R-G

Overview

The XC6808BND28R-G is a single-cell lithium-ion battery linear charger IC manufactured by Torex Semiconductor. It integrates a charge termination function and operates with an input voltage range of 4.20V to 4.40V. The device supports battery temperature detection via an external thermistor, ensuring safe charging conditions. It features a constant current/constant voltage (CC/CV) charging profile with programmable charge current. The IC includes internal circuitry for automatic recharge control and charge status indication.

Feature Summary

• Integrates battery temperature detection circuitry using an external NTC thermistor to monitor cell temperature during the charging process.
• Provides automatic recharge functionality that initiates charging when the battery voltage drops below a specific threshold after full charge completion.
• Includes charge status output pin to indicate whether the battery is currently being charged or has reached the termination state.

Applications

• Single-cell lithium-ion battery charging in portable electronic devices
• Power management systems requiring integrated thermal monitoring
• Consumer electronics with limited board space for power components
