The XC6808AND28R-G is a 4.20V/4.35V/4.40V single-cell Li-battery linear charger IC with battery temperature detection manufactured by Torex Semiconductor. It is designed to provide charging currents up to 1 A, and is mainly used for the charging of portable devices such as mobile phones, tablets, and digital cameras. It features low current consumption in standby mode, precise output voltage control, short-circuit protection (SCP), low ripple, and over-temperature protection (OTP). It also is equipped with a battery temperature detector, allowing the system to automatically control charging current and monitor the battery temperature. It also has an error amplifier that can be used to detect abnormal battery voltage. The XC6808AND28R-G also features thermal shutdown and sleep mode functions.
