PMIC supervisors, such as the BU4230FVE-TR, are integrated circuits that are used to monitor supply voltages and reset microcontrollers. As the name implies, their primary purpose is to supervise the power supply and reset system in microcontroller applications. In this article, we will discuss the application field and working principle of the BU4230FVE-TR.

The BU4230FVE-TR is a RoHS-compliant real-time electrical supervisor that has a wide range of supply voltage monitoring and reset functions. It is designed to provide circuit protection and reset capabilities for a variety of microcontroller-based applications. The BU4230FVE-TR is suitable for use in the automotive, industrial, telecommunications, and consumer products markets.

The BU4230FVE-TR has several features that make it suitable for a variety of applications. It has a wide supply voltage monitoring range of 4.5V to 25V, and it can also operate over a temperature range of -40°C to +125°C. The BU4230FVE-TR has an adjustable time delay of up to 6 seconds and an output reset pin that can be used to reset other components in the system. The BU4230FVE-TR also has an independent fail-safe voltage monitor and adjustable trip point for overvoltage protection. This protection prevents poor power supply conditions from damaging the system.

The BU4230FVE-TR works by sensing the voltage level of the power supply and comparing it with a pre-set voltage level. If the voltage level falls below the pre-set level, the BU4230FVE-TR triggers the reset output pin. This pin can then be used to reset the microcontroller or other components in the system. The adjustable time delay feature allows the user to set an appropriate reset time for the system, depending on the application.

In summary, the BU4230FVE-TR is a RoHS-compliant, real-time electrical supervisor. It is suitable for use in a wide range of applications including automotive, industrial, telecommunications and consumer products. The BU4230FVE-TR has a wide supply voltage monitoring range, an adjustable time delay and an independent fail-safe voltage monitor. It works by sensing the voltage level of the power supply and triggering the reset output pin if it falls below the pre-set voltage level. This reset output pin can be used to reset other components in the system.
