VN750-12-E

The VN750-12-E is an important member in the family of Power Management IC (PMIC) devices and has been widely used in a variety of applications. It is a multi-purpose integrated switch and load driver devices, primarily used to handle power distribution and enable/disable different loads. This article explores the application field and working principle of the VN750-12-E.

Let’s first dig into its application field.
The VN750-12-E has a wide range of applications, including automatic power switching between multiple power sources, controlling electrical loads, and voltage and current measurement. The device supports operations from −40° to +85°C temperatures and is widely utilized in automotive, telecom, industrial, computer, and consumer applications.

The working principle of the VN750-12-E.
The VN750-12-E consists of two main components – an integrated power distribution switch and a load driver. The power distribution switch is designed to automatically switch between multiple power sources and allow current to be drawn from a chosen source. When the appropriate power source is found, the current is drawn from it and the load driver is activated. The load driver is designed to enable and disable electrical loads as needed. It is a three-input driver and can be used to drive two loads simultaneously. The driver is controlled by the power switch and is activated when the power switch has identified the correct power source. It then determines which load to enable or disable based on the data sent by the power switch and the user’s input.

Conclusion.
In conclusion, the VN750-12-E is an integrated power distribution switch and load driver device. It has a wide range of applications and is used to power and control electrical loads. The device features a power distribution switch that is designed to switch between multiple power sources and draw current from the right one. It is also equipped with a load driver that enables and disables electrical loads based on input from the power switch.
