Power management integrated circuit (PMIC) is a device which provides integrated power distribution, regulation and management for integrated circuits (ICs) and other applications. It is a major component of an electronic system and has various features to help system-level design, ranging from functions such as power supply sequencing and control, system power regulation, thermal management, load sharing and protection. Different kinds of PMICs offer a wide range of functions and features, including power distribution switches, load drivers, voltage reference, voltage regulators, and more.

VNQ7140AJTR-E is a power distribution switch, load driver PMIC produced by Vishay Intertechnology. It is part of Vishay’s family of low-voltage and high-efficiency PMICs, and it combines both power distribution switch and load driver functions in a single-packaged IC. The device has a low voltage/current rating of 0.32V/54mA, a high voltage/current rating of 1.8V/25mA, and an operating temperature range from -40°C to +85°C. VNQ7140AJTR-E is designed for use in industrial, healthcare, and other applications which require reliable and efficient power-on sequencing and sequencing switching.

The core working principle of the VNQ7140AJTR-E PMIC is to provide integrated power distribution and regulation through the use of power distribution switch and load driver (LDM) technology. The power distribution switches are used to control, switch, and protect the load while the load drivers provide the necessary control, output voltage and current, and voltage feedback. The load is monitored by an internal loop that senses the load current, performs safety checks, and then provides feedback to the supply voltage, allowing the power supply to adjust its output voltage and current accordingly. The VNQ7140AJTR-E PMIC also provides a range of power management features such as load sharing, power-on sequencing and sequencing control, thermal protection, and overvoltage protection.

The power distribution switches used in the VNQ7140AJTR-E PMIC are based on MOSFET technology with a wide range of available configurations. The devices are designed for use in high-temperature, high-voltage and high-frequency applications, and are characterized for their low power dissipation, fast switching speeds, and high ESD protection. The load drivers used in the VNQ7140AJTR-E PMIC are designed to provide high precision voltage and current control, allowing users to accurately set the desired parameters. The loads themselves are monitored using an integrated temperature sensor which allows the system to be tuned and optimized for safe operation.

The VNQ7140AJTR-E PMIC is suitable for use in a wide range of applications requiring efficient power distribution, regulation and management. Its combination of power distribution switch and load driver technology make it an ideal solution for industrial, healthcare and other applications requiring reliable and efficient power-on sequencing and sequencing switching. The device’s wide temperature range and wide range of available power management features make it suitable for high-temperature and high-frequency applications, while its low voltage/current rating and high ESD protection ensure reliable use in demanding applications.
