AP2171WG-7

The AP2171WG-7 is a power management integrated circuit (PMIC) designed to switch, regulate and manage the power supply to various parts of a system in an efficient, reliable and cost-effective manner. The AP2171WG-7 is designed to integrate several distinct functions of power distribution, load switching and monitoring, power supply sequencing and other control logic. In order to understand its application field and working principle, it is helpful to consider its features and components.

Features: The AP2171WG-7 features a voltage range of 8V to 30V, with a maximum power rating of 6.5W. It uses a Buck-Boost topology, with a synchronous internal MOSFET switch designed to enable higher efficiency than other conventional PMICs. It also includes an internal linear regulator, which simplifies the design process by not requiring additional external components. Furthermore, it includes an advanced power management and sequence controller, which can monitor and control various power rails and load switching processes. In addition, it provides programmable over-voltage and under-voltage protection, as well as over-temperature shutdown protection.

Components: The core components of the AP2171WG-7 include the Buck-Boost topology, the internal MOSFET switch, the linear regulator, and the power management and sequence controller. The purpose of the Buck-Boost topology is to efficiently regulate and switch an input voltage range from 8V to 30V to the desired output voltage. The internal MOSFET switch is designed to drive both high and low-side devices, and provides protection against over-driving and short-circuiting. The linear regulator is designed to regulate the input voltage to a configured target voltage, and is able to regulate a wide input voltage range. Finally, the power management and sequence controller provides a range of features, such as monitoring and controlling of various power rails, load switching processes and over-voltage and under-voltage protection, and can also be used to sequence various power rails on and off.

Application Field: The AP2171WG-7 PMIC is ideal for use in battery management systems, Smart camera systems, automotive applications, desktop PCs, and applications such as tablets and mobile phones. It is also suitable for use in safety-critical applications such as those requiring PMICs with over-voltage and over-temperature protection.

Working Principle: The AP2171WG-7 works by first receiving an input voltage, typically in the range of 8V to 30V. This input voltage is then regulated by the internal linear regulator and Buck-Boost topology, and is converted to the desired output voltage. The internal MOSFET switch is then used to drive both high and low-side devices, and provides protection against over-driving and short-circuiting. Finally, the advanced power management and sequence controller monitors the various power rails and load switching processes, and can be used to sequence various power rails on and off.

As a power management integrated circuit, the AP2171WG-7 offers an efficient, reliable and cost-effective solution for power distribution, load switching and monitoring, power supply sequencing and other control logic. It has a wide range of applications, including battery management systems, desktop PCs, smart cameras and automotive applications. With its Buck-Boost topology, internal MOSFET switch, internal linear regulator and advanced power management and sequence controller, it is capable of efficiently and reliably regulating, switching and monitoring the power supply.
