BU4810F-TR

Supervisors Overview

The BU4810F-TR is a standard voltage detector manufactured by ROHM Semiconductor, designed for monitoring supply voltages in electronic circuits. It features an open-drain output type and operates within a reset active voltage range of 0.7 V to 7 V. The device has a typical under-voltage detection voltage of 1.0 V with a precision of ±1%. It consumes 0.40 μA in the ON state and 0.55 μA in the OFF state at VDET=4.8V. The component supports a temperature range from -40°C to 125°C and is housed in an SSOP5 package.

Supervisors Feature Summary

• Provides precise under-voltage detection with high accuracy
• Features low power consumption suitable for battery-operated devices
• Offers open-drain output for flexible interface compatibility

Supervisors Applications

• Portable electronic devices requiring voltage supervision
• Battery-powered systems needing low standby current
• General-purpose circuit protection against under-voltage conditions

Supervisors Procurement Notes

Verify the specific suffix and package variant when ordering, as availability may vary. Confirm that the component meets RoHS compliance requirements for your region. Check the latest supply status, as this part may be subject to discontinuation or limited production runs. Ensure compatibility with existing design specifications before procurement.

Supervisors Selection Notes

Select this component for applications requiring a fixed 1.0 V detection threshold. Consider the SSOP5 package size constraints during PCB layout. Evaluate the open-drain output capability against system logic levels. Compare power consumption metrics with alternative detectors if ultra-low current is critical.

Supervisors Part Context

This part belongs to the BU48 series of voltage detectors from ROHM Semiconductor. It is functionally similar to the BD5210G-1, though differences exist in reset delay and output current capabilities. The BU4810F-TR is designated as Not Recommended for New Designs (NRND), indicating it is being phased out in favor of newer alternatives.

Supervisors Replacement Considerations

The BD5210G-1 is listed as a similar specification replacement with the same package. Verify functional differences such as adjustable delay and output current ratings before substitution.
