Power management integrated circuits (PMICs) play an important role in modern electronics as they manage voltage and electrical current to other circuits. PMICs are typically used in battery-powered consumer electronics such as smartphones, tablets, and watches, where efficient power management is essential in extending device life. In this article, we will take a look at one particular type of PMIC: battery charger. Specifically, the ADP5090ACPZ-2-R7, which is a battery charger IC from Analog Devices.

The ADP5090ACPZ-2-R7 is a fully integrated dual-cell Li-ion/Li-polymer battery charger IC for both high volume and industrial applications. It has two independent charging channels and is capable of supporting charging currents ranging from 100mA to 1.5A. It operates between an input voltage range of 3.6V to 12V and features an efficient synchronous PWM converter inside. The IC also supports battery temperature and over-current protection, as well as charge status control and charge complete detection.

The primary application of the ADP5090ACPZ-2-R7 is in portable consumer electronics, such as smartphones, tablet PCs, and digital cameras. It is also used in GPS navigation systems, wearable electronics, medical instruments and security systems. The IC can also be used in industrial and automotive applications, where it is primarily used for battery charging.

The ADP5090ACPZ-2-R7 employs a synchronous PWM converter to convert the input voltage to the desired output voltage. It supports both charge only and charge plus maintenance modes. The charge only mode is used to charge a battery quickly and the charge plus maintenance mode is used to maintain the level of charge in the battery over time. The IC also features a low quiescent sleep current and a power saving shut-down mode. This helps to maximize battery life and reduce overall power consumption.

The IC is also equipped with a wide range of safety features including over-voltage and over-current protection. It also supports advanced thermal shutdown and softstart functions to prevent possible damage to connected circuits. Additionally, the IC includes an accurate and reliable charge-complete detection feature that can be used to monitor the charge state of the connected battery.

In conclusion, the ADP5090ACPZ-2-R7 is a versatile and powerful battery charger IC from Analog Devices. It is primarily used in portable consumer electronics, but it can also be used in industrial and automotive applications. The IC employs a synchronous PWM converter and is equipped with a wide range of safety features and advanced power management features. All of these features make it an ideal choice for battery powered electronics applications.
