In the development of modern electronic applications, power management integrated circuits (PMIC) play an important role in providing reliable power supply solutions. It has a wide range of applications in the industry, mainly in industrial and consumer electronic devices, including mobile phones, tablets, notebooks, servers, smart TVs, wearables, and camera drones. Due to the continuing improvement of IC process and the miniaturization of IC layout, the applications covered by PMIC have become more and more extensive.

As an important part of PMIC, battery management (BMS) is responsible for improving battery performance. BMS is a multi-function chip designed to manage the power used by a battery and ensure that the battery is properly used. Among the various battery management ICs, TPS65023RSBR is a high-efficiency battery system-on-chip (SoC) that integrates all power control functions. It includes a step-down DC-DC main DC charger and a buck DC-DC connector, as well as charging, monitoring and protection functions.

TPS65023RSBR can be used in electric vehicles, drones, self-balancing vehicles, robots, handheld equipment, power tools and other battery-powered devices. Its main function is to provide a constant and stable voltage to the device powered by battery, and maintain the battery in a safe state. The TPS65023RSBR also provides charging using an external power supply, such as AC/DC wall adapter, solar panel, or USB port. In this way, the cost of battery replacement can be greatly reduced.

The TPS65023RSBR is composed of three power blocks, a power controller, a power buck switch, and a sensing and protection block. The power controller block is mainly responsible for generating a power supply circuit according to the user\'s setting, and providing a constant and stable voltage for the external load. It can be programmed to obtain a wide range of output voltages from 0.7V to 19V or higher, and can support up to 5 Amps of current.

The power buck switch, also known as synchronous rectifier, is used to convert the battery into regulated voltage. It works by comparing the input voltage and the output voltage, then adjusting the duty cycle to achieve a suitable output voltage. This helps to reduce the voltage drop, thus increasing the overall efficiency of the system and improving the battery\'s life.

The sensing and protection block includes a sense amplifier, a current sense amplifier, and a protection circuit. The sense amplifier monitors the output voltage and battery voltage. When the output voltage is too high or too low, the sense amplifier will send a signal to adjust the loop control to remain within the safe operating range. The current sense amplifier monitors the current of the output voltage, and when it is over the current limit, it will trigger the protection circuit to shut down the device.

In short, the TPS65023RSBR is a multi-function SoC that provides a variety of power control functions, including switching and protection, aimed at efficient battery management. It is suitable for a variety of applications, including electric vehicles, drones, batteries, power tools and more. Its combination of power control, charging, monitoring and protection functions can greatly improve the performance and reliability of battery-powered devices.
