Introduction to BU52061NVX-TR

The BU52061NVX-TR is a Magnetic Sensors – Switches (Solid State). It is a fully integrated solid-state Hall magnetic switch tailored for battery protection and user detect applications. This device has a built-in Hall-voltage generator, temperature-compensated Schmitt Trigger and constant-current source with Overtemperature Protection.

Application Field of BU52061NVX-TR

This solid-state Hall switch finds primary applications in the fields of battery protection and user detection, as it offers improved performance and reliability over mechanical switches. The thermal range of the device is -40°C to 85°C, making it well-suited for operating in various environmental conditions.The device provides a battery protection function for when the detecting voltage after passing through the current source reaches the switch-on threshold voltage. This can be used in smart charging systems that require high voltage and current safety and stability. It can also be used in applications that require lower detecting voltage and higher detecting current, such as user detection, enabling the command to be read with higher reliability.

Working Principle of BU52061NVX-TR

When a magnetic field is present around the solid-state switch, the Hall voltage is generated, which is amplified and output from the Schmitt-trigger circuit. The BU52061NVX-TR features low-power and low-voltage consuming characteristics with low-offset Schmitt-trigger circuit. With Overtemperature Protection, the robust Hall switch is suitable for use in various applications, including front-panel protection switches, DC/DC and AC/DC converters, chargers, LED failure detection, and overcurrent protected power supplies.The device has an integrated constant current source which converts the Hall voltage into proportional current for reliable switch detecting. The detecting current can exceed 10 mA and is much higher than the current produced in a conventional Hall element. This improvement in detecting current also reduces the influence of the environment (magnetism, noise, temperature) on switch operation.

Conclusion

In conclusion, the BU52061NVX-TR is a Magnetic Sensors – Switches (Solid State) that can be used in several applications, including battery protection and user detection, thanks to its Schmitt-trigger circuit, current source, and Overtemperature Protection. This feature-rich, robust device also provides reliable switch detecting with a higher detecting current than typical Hall elements, while consuming low-power and low-voltage.
