BD4825G-TR

Overview

The BD4825G-TR is a standard voltage detector manufactured by Rohm Semiconductor, designed for monitoring single-channel power supply voltages. It features an open-drain output and provides a low-active reset signal upon detecting under-voltage conditions. The device operates within a supply voltage range of 1.2 V to 10 V and includes a typical detection threshold of 2.5 V with ±1% accuracy. It supports a wide operating temperature range from -40°C to 105°C and is housed in a compact 5-SSOP package.

Feature Summary

• Provides simple reset or power-on reset functionality for monitored circuits
• Features open-drain output compatible with various logic families
• Operates across a wide supply voltage range up to 10 V

Applications

• Microcontroller system supervision
• Battery-powered device voltage monitoring
• Embedded system power management

Procurement Notes

Verify component authenticity through authorized distributors. Confirm RoHS compliance status as per current regulatory requirements. Check datasheet revisions for any updates to electrical characteristics or pin configurations before integration into final designs.

Selection Notes

Select this component when a fixed 2.5 V threshold is required for under-voltage detection. Ensure the open-drain output configuration matches the downstream circuit's pull-up requirements. Consider the 5-SSOP package dimensions for PCB layout constraints.

Part Context

This part belongs to the BD48 series of standard voltage detectors from Rohm Semiconductor. It is functionally similar to other parts in the family but distinguished by its specific 2.5 V detection threshold and lack of manual reset or watchdog timer features.

Replacement Considerations

BD5225G-1 is listed as a replacement with the same SSOP5 package and 2.5 V threshold, though it offers adjustable delay and different current specifications.
