BU4313G-TR

Overview

The BU4313G-TR is a CMOS low-voltage detector manufactured by ROHM Semiconductor, designed for monitoring single-input voltage levels. It operates within a supply voltage range up to 7 V and features an adjustable reset delay time. The device provides a CMOS output type and lacks manual reset, watchdog timer, or battery backup switch functionalities. It is housed in an SSOP-5 surface-mount package and supports operation at minimum temperatures of -40°C. The typical threshold voltage is specified at 1.3 V.

Feature Summary

• CMOS output interface for digital logic compatibility
• Adjustable reset delay timing capability
• Single-channel voltage monitoring input
• Surface-mount SSOP-5 packaging

Applications

• Portable electronic device power management
• Battery-operated system supervision
• Microcontroller reset circuit generation

Procurement Notes

Verify the Not Recommended for New Designs (NRND) status before integration into new products. Confirm RoHS compliance details via the official datasheet. Ensure the SSOP-5 package dimensions match the target PCB footprint. Validate the 1.3 V threshold against specific application requirements.

Selection Notes

Select this component when a low-voltage detection function with adjustable delay is required in a compact SSOP-5 form factor. Consider the CMOS output drive capability and the absence of additional features like watchdog timers. Evaluate the 7 V maximum supply voltage limit against the system's operating range.

Part Context

This part belongs to the BU43xx series of voltage detectors from ROHM Semiconductor. It shares functional similarities with other parts in the family but is distinguished by its specific 1.3 V threshold and adjustable delay characteristics within the SSOP-5 package configuration.

Replacement Considerations

The BD5211G-1 is listed as a similar level replacement with the same pinout and package. Verify electrical parameter alignment and confirm the recommended status of the substitute part.
