The XC6805A4E14R-G battery charger is a device used to charge and manage lithium-ion batteries. It is part of the power management integrated circuit (PMIC) family and is commonly used for portable electronic devices. The XC6805A4E14R-G is a cost-effective and highly integrated solution for single-cell lithium-ion (Li-ion) battery charging. It features a high accuracy band gap reference, a wide voltage range, and a constant-current/constant-voltage charging algorithm.

The XC6805A4E14R-G device is designed to charge a single cell Li-ion and Lithium-Polymer (LiPo) battery from a USB port, an adapter, or any other suitable supply. The charger operates with a switching regulator, enabling the charge current to be increased or decreased in incremental steps based on temperature and Vcol voltage. The XC6805A4E14R-G controller is capable of handling a wide range of input voltages, from 4.5V to 20V. It also features an integrated battery temperature sensor, allowing the charge current to be adjusted if the battery temperature exceeds a certain threshold.

The XC6805A4E14R-G has a wide set of safety features to ensure protection against over-voltage and over-current conditions. These include input over-voltage protection (OVP), charging current and voltage regulation, and under-voltage protection. This integrated IC also supports low-voltage battery pre-charging and drain back to avoid over-discharging of the cells. Additionally, the XC6805A4E14R-G can deliver a constant output current, regardless of the input voltage, thus reducing energy consumption.

The XC6805A4E14R-G supports a number of communication interfaces, providing an easy-to-use interface for monitoring the charging process. It features an I2C interface, which is used to monitor charging status, as well as output voltage, temperature and remaining capacity. The output voltage, current and battery temperature can also be monitored using a System Monitor (SYSMON) input. This enables the user to adjust the battery charging parameters remotely, allowing for optimized charging performance.

The XC6805A4E14R-G is suitable for a wide range of applications, including mobile phones, PDAs, digital cameras, portable DVD players and other portable electronic devices. With its high accuracy, high efficiency, and wide input voltage range, the XC6805A4E14R-G is a great choice for managing Li-ion batteries in these devices. It is an economical solution for a wide range of applications, providing reliable protection and optimal performance.
