Power supply management has always been a difficult task in electronic design. The AP9211SA-AD-HAC-7 is a high-performance charger/Power Management Integrated Circuit (PMIC) targeted for use in automated rechargeable battery support applications, such as laptops, tablets, and smartphones. Its small size and advanced integrated features make it an ideal solution for a wide range of applications. In this article, we’ll discuss the AP9211SA-AD-HAC-7 application field and working principle.

The AP9211SA-AD-HAC-7 provides integrated power supply management for power sources from 5V DC to 12V DC+/-3% input. It integrates two separate high-efficiency synchronous buck/boost converters with up to 3A/1.5A output current (respectively) and three independent linear chargers with up to 2A/1A output current. It also provides integrated over-voltage and over-current protection to protect the device from damage.

The AP9211SA-AD-HAC-7 features Battery Profile Detection (BPD) which enables automatic detection of the battery type and enables optimized charging parameters to get the most out of the battery. It also has a high-efficiency step-up circuit that allows designers to easily add fast charging capability (up to 5A) for quick battery charging.

The AP9211SA-AD-HAC-7 is designed to meet the requirements of medium- to high-end battery-powered systems. It is ideal for applications such as: laptops, tablets, digital cameras, remote control toys, power packs and other power management applications.

The AP9211SA-AD-HAC-7 uses a complex power-management algorithm to efficiently manage the battery charging process.

When the device is powered up, the AP9211SA-AD-HAC-7 will detect the battery type, configure the charging parameters and start the charging process.

The primary power path of the AP9211SA-AD-HAC-7 consists of two separate synchronous buck/boost converters, which efficiently regulate the input voltage and current to the correct level for the connected power source.

The second power pathway of the AP9211SA-AD-HAC-7 consists of three independent linear chargers, which provide sufficient current for charging the battery.

The AP9211SA-AD-HAC-7 is also integrated with over-voltage and over-current protection to prevent damage to the device in case of an over-voltage or over-current condition.

The AP9211SA-AD-HAC-7 also includes several internal control signals that enable the communication between the AP9211SA-AD-HAC-7 and the external microcontroller. This allows the external CPU to monitor and control the charging process, as well as manage any system parameters that may be adjustable.

The AP9211SA-AD-HAC-7 enables accurate and efficient charging of the battery to ensure the highest battery lifetime and performance.
