Modern industrial technologies require advanced power views and accurate power management. The VN7140AJ-E, a power management integrated circuit (PMIC) from Vishay Intertechnology, is a widely applicable solution for various tasks in power management. This PMIC can be used for power switching, providing load drivers, and increasing efficiency and reliability for the circuit. The different operating principles and usage of the VN7140AJ-E will be elucidated below.

Application Field

The VN7140AJ-E PMIC is mainly used in power management applications, such as power switching, current & voltage regulation, power distribution, debugging of electronic circuits, and motor control. This PMIC is a 3-phase output device providing adjustable current limiter, local power off, input power on/off control, and output power on/off control. The VN7140AJ-E provides superior braking and reverse current protection, and thus is well suited for advanced motor control applications.

In addition, the PMIC has a wide input voltage range, making it well-suited for a range of applications in various conditions. This includes solar energy, wind energy, battery charger/backup systems, renewable energy, triggering systems, and smart home/building control systems. Moreover, the PMIC is designed for cost/space-efficient applications that require proper power management such as in AC/DC converters and switch-mode power supplies (SMPS).

Working Principle

The VN7140AJ-E provides three-phase regulated output voltage and features an embedded current limiter, an input current limiter, and a soft-start. All three of these components are configured through the device over-temperature (OT) pin. Configuring the OT pin determines the functionality of the PMIC, enabling the chip to operate in either continuous or single-pulse mode.

In addition, the device includes an array of protection features that ensure reliable and safe operation. These features provide reverse current protection, short circuit and undervoltage protection, as well as a wide voltage range compensation. This makes the VN7140AJ-E suitable for motor control circuits wherein the maximum current load can be accurately determined and maintained.

The VN7140AJ-E is designed with built-in overvoltage protection module (OPM). The OPM detects the overvoltage and triggers the OTP pin to activate the local power off function. This allows for a close load loop for high voltage applications, such as battery charging and power supply systems. The LED indicators also assists in debugging mode, allowing users to detect the device states.

Conclusion

In summary, VN7140AJ-E is a comprehensive PMIC featuring adjustable current and voltage regulation, power distribution, and local power on/off control. This makes it a highly helpful solution for applications in power switching, voltage regulation, current regulation, motor control, power distribution, and debugging of electronic circuits. The protection features ensure reliability and safety of the device. Moreover, the adjustable current limiter and soft-start make it extremely space- and cost-efficient.
