BD5356G-TR

Overview

The BD5356G-TR is a single-channel voltage detector manufactured by ROHM Semiconductor, designed for power supply supervision. It features a fixed detection threshold of 5.6 V with an accuracy of ±1%. The device operates within a reset active voltage range of 0.95 V to 10 V and utilizes a CMOS output type. It is housed in a VSOF-5 package and supports surface mount installation. The component functions without manual reset or watchdog timer capabilities, maintaining operation across a temperature range of -40°C to +105°C.

Feature Summary

• Provides precise monitoring of a single input voltage channel using a fixed threshold.
• Delivers system reset signals via a CMOS output interface.
• Operates reliably across extended industrial temperature ranges.

Applications

• Power supply support circuits requiring voltage supervision
• Embedded systems needing under-voltage detection
• Industrial control equipment monitoring

Procurement Notes

Verify the obsolete status and last-time-buy availability through official ROHM channels before finalizing procurement plans. Confirm that the VSOF-5 package dimensions match the target PCB footprint. Ensure compliance with RoHS directives and check for any regional distribution restrictions that may affect sourcing logistics.

Selection Notes

Select this component when a fixed 5.6 V threshold is required for single-channel supervision. The CMOS output suits digital logic interfaces. Consider the VSOF-5 package constraints for board space. Verify that the absence of adjustable delay or manual reset meets the specific application timing requirements.

Part Context

This part belongs to the BD53 series of supervisory circuits from ROHM Semiconductor. It serves as a dedicated voltage detector for monitoring power rails in electronic systems. The series typically offers various threshold options to accommodate different standard voltage levels in consumer and industrial electronics.

Replacement Considerations

BD5250G-1TR is listed as a recommended replacement with the same pinout. Note that the substitute has a different detection threshold (5.0 V) and open-drain output, requiring circuit review.
