Introduction to BU4921FVE-TR

BU4921FVE-TR is a three-channel, voltage-detection electronic device, a type of supervisor that can be used for voltage detection for medium, high and super-high voltage applications. It is designed to sense and monitor the voltage of three power-supply lines, low-voltage systems and back-up power. This device offers superior voltage detection capabilities compared to traditional methods. It is capable of detecting very small changes in voltage levels, and its output can be used to trip devices or control other electronic devices.

Features & Benefits of BU4921FVE-TR

The BU4921FVE-TR includes a number of features that make it suitable for both medium and high voltage applications. Firstly, it has an adjustable detection voltage that can be set from 0.3V to 20V, which makes it suitable for a wide range of applications. Furthermore, it has two different output styles. A cMOS output style is available that provides a low voltage level signal when the voltage falls below an adjustable threshold, and a push-pull output style that provides a high voltage level signal when the voltage falls below the same threshold. The combination of these two output styles gives the device great flexibility in providing detection signals for multiple voltage levels without requiring additional components.The device is also equipped with a built-in digital temperature sensor that can be used to measure and monitor temperature fluctuations in order to prevent over-voltage or over-temperature conditions. It also has built-in self-diagnosis and jitter-enhanced circuitry which improves reliability and stability. The BU4921FVE-TR can be used in a range of applications, including voltage detection, power supply systems, overvoltage or undervoltage protection, and temperature monitoring systems.

Applications of BU4921FVE-TR

The BU4921FVE-TR is suitable for a wide range of applications due to its superior features and performance characteristics. It can be used for voltage detection for medium, high and super-high voltage applications. Moreover, it can be used in power supplies, low voltage systems and back-up power, as well as for overvoltage and undervoltage protection and temperature monitoring systems. In power supply systems, the BU4921FVE-TR can be used to sense and monitor the voltage of three power lines and detect very small changes in voltage levels. This can help to prevent damage due to overvoltage or undervoltage conditions. In low voltage systems, the device can be used to detect voltage levels below a certain threshold and trip a device or control other circuits. This can improve the reliability of the system and prevent it from experiencing any damage related to overvoltage or undervoltage conditions. In back-up power systems, the BU4921FVE-TR can be used to detect very small changes in the voltage supplied by the back-up power source and allow the system to switch to another power source in the event of failure. This can increase the system’s reliability and reduce the possibility of a power outage or electrical damage due to overvoltage or undervoltage conditions.

Working Principle of BU4921FVE-TR

The BU4921FVE-TR has an adjustable detection voltage range and can detect voltages of up to 20V. The device has three operational channels, each of which can be set to a specific voltage level. The device is triggered when the voltage on the corresponding channel is below the threshold voltage. The output of the device is then used to trip a device or control other circuits. The device is also equipped with a built-in digital temperature sensor. This sensor is used to measure the ambient temperature and can be used to prevent over-volatge or over-temperature conditions. The device also includes jitter-enhanced circuitry to improve stability. This circuitry is used to reduce any static fluctuations that may occur in the output of the device, ensuring that the output is more accurate and reliable.

Conclusion

BU4921FVE-TR is a three-channel voltage-detection supervisor that can be used for medium, high and super-high voltage applications. It has adjustable detection voltage, two output styles, built-in digital temperature sensor, self-diagnosis and jitter-enhanced circuitry to improve reliability and performance. The device has a wide range of applications such as power supply systems, low voltage systems and back-up power, overvoltage or under voltage protection and temperature monitoring systems.
