Introduction

AAT3635IUH-1-T2 is a PMIC (Power Management IC) developed for battery chargers, providing dual-channel one-way buck control and fast charge control. It is designed to meet the high power requirements of today’s high-end consumer electronics products, including fast-charging mobile phones, tablets, robots, and wearable devices. This article will discuss the application field and working principle of the AAT3635IUH-1-T2.

Application field of AAT3635IUH-1-T2

The AAT3635IUH-1-T2 is designed for use in battery chargers, providing two buck channels in hardware and two high-level software control channels. It is particularly well-suited for fast charging applications, due to its high-efficiency pulse-width modulation and built-in over-current protection. It provides support for optimal current, voltage and temperature control, while providing automatic protection against overloads, short-circuits, and over-voltage.In addition, the AAT3635IUH-1-T2 is designed for use in a variety of portable and IoT (Internet of Things) devices that require efficient charging and power management. This includes mobile phones, tablets, robots, and wearable devices, as well as digital media players, satellites, and more.

Working Principle of AAT3635IUH-1-T2

The AAT3635IUH-1-T2 is a top-level power management chip (PMIC) for battery chargers. It uses a dual-channel, one-way buck-control design with fast charge control. It can accurately control the voltage, current and temperature of the device, providing optimal energy efficiency and reliable protection against over-current, short-circuit and over-voltage conditions.The chip consists of two channels: one channel with a fixed voltage output, and the other with an adjustable voltage output. The chip also has a built-in pulse-width modulation (PWM) controller, which ensures efficient power delivery. The fixed voltage channel is designed to provide adjustable current, while the adjustable voltage channel is designed to provide adjustable voltage. Both channels provide constant current and are controlled by the on-board MCU. The fast charge control allows for quick charge rates, while the built-in multicorner boost controller provides a high level of efficiency. The chip also includes an over-current protection circuit, which can detect any faults, such as a short circuit or a too-high voltage, and shut down the system for protection.

Conclusion

The AAT3635IUH-1-T2 is a top-level PMIC for battery chargers, providing dual-channel one-way buck control and fast charge control. It is especially well-suited for mobile phones, tablets, robots, and wearable devices, as well as other portable and IoT devices. It ensures efficient power delivery by virtue of its built-in pulse-width modulation controller, and provides built-in protection against overloads, short-circuits and over-voltage conditions.
