BU4825FVE-TR

Supervisors Overview

The BU4825FVE-TR is a CMOS voltage detector manufactured by Rohm Semiconductor, designed for supervisory circuit applications. It features a fixed detection threshold voltage of 2.5V with an accuracy of ±1%. The device operates within a supply voltage range up to 7V and supports an open-drain output configuration. It functions as a simple reset/power-on reset monitor without manual reset or watchdog timer capabilities. The component is available in a VSOF-5 package and is rated for operation across a temperature range of -40°C to +125°C.

Supervisors Feature Summary

• Fixed 2.5V detection threshold with ±1% precision
• Open-drain output interface for system reset signaling
• Extended industrial operating temperature range

Supervisors Applications

• Power supply monitoring in electronic systems
• Voltage supervision for microcontroller reset circuits
• Low-voltage detection in portable devices

Supervisors Procurement Notes

Verify the specific suffix 'FVE' against the manufacturer's current datasheet to confirm package type and electrical characteristics match project requirements. Confirm RoHS compliance status and check for any end-of-life notifications or last-time-buy recommendations from Rohm Semiconductor before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a fixed 2.5V threshold is required for power supervision. Ensure the open-drain output capability aligns with the target system's logic levels. Verify that the VSOF-5 package dimensions fit the PCB layout constraints and that the operating temperature range meets the environmental conditions of the application.

Supervisors Part Context

This part belongs to the BU48xx series of standard voltage detectors from Rohm Semiconductor. These ICs are designed for low-power applications requiring precise voltage monitoring. The BU4825 variant specifically targets systems needing a 2.5V reference point for reliable reset generation under varying supply conditions.

Supervisors Replacement Considerations

BD5225G-1 is listed as a similar specification replacement with comparable 2.5V threshold and open-drain output, though it utilizes an SSOP5 package instead of VSOF5.
