BU4931F-TR

Introduction

The BU4931F-TR is a microprocessor supervisory integrated circuit which features a low current, low voltage detector, post-reset voltage output and manual reset signal pin. It is mainly used in battery-powered systems, computer systems and other embedded system applications, whose reset supervisor requires low power consumption, low standby current and reliable protection against system crashes. This device is suitable for various designs that need to monitor the system’s supply voltage and provide timely corrective action when its voltage goes below a safe limit.

Application Fields

One of the primary uses of this device is as a reset supervisor in battery-powered systems, where it can help prevent unexpected system shutdowns due to power loss. It is also well-suited for use in computer systems with post-reset voltage output, manual reset input or both. Additionally, it is used in MCU-based embedded control systems, where it can be used to reset the MCU if it encounters an unexpected system crash.

The BU4931F-TR is also commonly used in consumer electronics, automotive systems, industrial process control systems and medical equipment, where it can help prevent system faults due to power failure. It is also useful in applications where a manual reset input is required in order to reset the system.

Working Principle

The BU4931F-TR is an integrated circuit that monitors the system’s supply voltage and provides a post-reset voltage output or a manual reset signal pin if the supply voltage falls below a safe limit. The post-reset output provides a reset signal to the microprocessor or other system components when the supply voltage falls below a set threshold. The manual reset input allows the user to manually reset the system if an unexpected condition occurs.

The BU4931F-TR also provides an adjustable voltage threshold and reset delay time which can greatly improve the reliability of the system. For example, the user can adjust the voltage threshold of the device in order to ensure that the system does not reset due to transient drops in the supply voltage. Additionally, the user can adjust the reset delay time in order to ensure that the system does not reset due to short transient conditions.

Conclusion

The BU4931F-TR is a microprocessor supervisory integrated circuit which features a low current, low voltage detector, post-reset voltage output and manual reset signal pin. It is mainly used in battery-powered systems, computer systems and other embedded system applications, whose reset supervisor requires low power consumption, low standby current and reliable protection against system crashes. This device can help protect the system from unexpected power loss and provide reliable reset signals when necessary.
