Application Field

The PT8A3515APE is designed to be used in single cell lithium-ion battery systems. It offers a number of advantages over discrete power management implementations, including reduced board complexity, improved system efficiency, and extended design life. The PT8A3515APE provides integrated voltage conversion functions, integrated switching power supplies, and a direct battery interface. These features make the PT8A3515APE ideal for applications such as notebook computer and LCD monitor power management, automotive power management and other portable products.

Working Principle

The PT8A3515APE integrates a number of power management functions, including voltage conversion, power supplies and interfacing with the battery. The integrated voltage conversion function provides adjustable output voltage from 1.2V to 5.5V with a fixed 5V output. The voltage conversion function is self regulating and requires no external components to adjust the output voltage. The integrated switch-mode power supplies provide fixed 3.3V and 1.0V outputs. During battery operation, the PT8A3515APE provides a direct interface to the battery, allowing the battery to be monitored for accuracy, charge rate and temperature. The integrated power management circuits also provide high efficiency and excellent thermal performance.

The PT8A3515APE includes several features to enhance the power management function, including an Automatic Battery Switchover (ABS) function, which automatically switch from the battery to an auxiliary power source when the battery is depleted, and a No Load Detection (NLD) function, which detects large current drain and shuts down all subsystems until the current drain returns to a safe level. The PT8A3515APE also includes integrated protection functions to protect the system from over-voltage, over-current, and over-temperature conditions.

The PT8A3515APE power management integrated circuit is an ideal solution for mobile and portable products. It provides integrated voltage conversion, power supplies, and a direct battery interface in a single chip solution, making it ideal for reducing system complexity and maximizing efficiency.
