BD5246FVE-TR

Overview

The BD5246FVE-TR is a voltage detector IC from ROHM Semiconductor, designed for monitoring supply voltages with an adjustable delay timer. It features a typical under-voltage detection threshold of 4.6V with ±1% precision. The device operates within a reset active voltage range of 0.95V to 10V and utilizes an open-drain output type with low-active reset state. Key electrical characteristics include a circuit current of 0.85μA when Vdet=4.8V. It is housed in a VSOF5 package and supports RoHS compliance.

Feature Summary

• Integrates an adjustable delay timer for customizable reset timing sequences.
• Provides high-precision voltage detection with ±1% tolerance on the threshold.
• Features an open-drain output structure compatible with various logic levels.
• Operates over a wide reset active voltage range from 0.95V to 10V.

Applications

• Monitoring power supply rails in embedded systems
• Providing reset signals for microcontrollers during power-up
• Supervising battery voltage levels in portable devices

Procurement Notes

Verify the specific suffix FVE against the official datasheet to confirm package type and pinout compatibility. Confirm RoHS status and supply status as the component may be subject to discontinuation notices. Ensure ordering quantities align with the manufacturer's minimum packing requirements for tape-and-reel packaging.

Selection Notes

Select this component when a precise 4.6V threshold with adjustable delay is required. Compare circuit current specifications against power constraints. Verify that the open-drain output configuration matches the system's input requirements. Check temperature range suitability for the intended operating environment.

Part Context

This part belongs to the BD52xx series of voltage detectors from ROHM Semiconductor. It shares functional similarities with other models in the family but is distinguished by its specific 4.6V threshold and VSOF5 packaging. The series is designed for general-purpose power supervision applications requiring reliable reset generation.

Replacement Considerations

BD5246G-1 is listed as a similar level replacement with the same pinout and package. Verify parameter differences such as vdet precision (±0.9%) and reset active voltage range (0.8V to 6V) before substitution.
