The AUR9807DIGD is a battery charger IC that belongs to the family of PMIC – Battery Chargers. It is an ideal solution for low-power portable applications, such as mobile phones, digital cameras, and smart wearables. The device is also suitable for automotive and industrial applications. The AUR9807DIGD is a 4-channel, integrated power management and battery charging unit that uses a single, four-cell lithium-ion (Li-ion) battery configuration.

The AUR9807DIGD supports a wide variety of charging programs, such as trickle, pre-charge, constant voltage, and constant current charging. It also features short-circuit protection, thermal cutoff, and accuracy protection, which makes it ideal for high-temperature charging environments. Furthermore, the device features a programmable charge current, voltage, and top-off for precise control of charging cycles.

The AUR9807DIGD is an integrated charging solution with an embedded battery fuel gauge and status indicator. The device features integrated voltage regulation with an adjustable power switch, which provides the system with maximum theoretical charge efficiency. It also features a high-precision A/D converter, temperature sensing, and a USB port for connectivity to external devices.

The device operates in four stages of charging: pre-charge, constant current, constant voltage, and top-off. During the pre-charge stage, it charges the battery up to a predetermined voltage level. In the constant current stage, the charger maintains a constant charging current and monitors the battery\'s charge level. When the charge level reaches a predetermined threshold, the charger switches to constant voltage mode and maintains the voltage to prevent overcharging. Finally, in the top-off stage, the charger monitors the battery\'s charge level and terminates the charging process when the battery is fully charged.

The AUR9807DIGD provides a wide range of features that make it an ideal solution for low-power, portable applications. Its integrated charge control and monitoring features ensure precise, safe charging of the battery, while its USB port provides a communications interface to external devices. Additionally, the device includes a programmable charge current, voltage, and top-off settings to ensure precise control of charging cycles, and its integrated power switch ensures maximum theoretical charge efficiency.
