BU4348G-TR

Overview

The BU4348G-TR is a CMOS voltage detector with an adjustable delay time, designed for supporting existing customers. It features a typical under-voltage detection voltage of 4.8V with ±1% precision. The reset active voltage range spans from 0.7V to 7V, utilizing a CMOS open-drain output type. The circuit consumes 0.40μA when active and 0.55μA when off at Vdet=4.8V. It operates within a temperature range of -40°C to +125°C and is housed in an SSOP-5 package.

Feature Summary

• Adjustable reset delay timer functionality
• CMOS open-drain output configuration
• Low power consumption design

Applications

• Supporting existing designs requiring voltage supervision
• Systems needing adjustable reset timing delays
• General purpose voltage monitoring applications

Procurement Notes

Verify the Not Recommended for New Designs (NRND) status before procurement. Confirm that the SSOP-5 package and specific 4.8V threshold align with legacy requirements. Ensure supply chain stability as this component is maintained for existing customer support rather than new development.

Selection Notes

Select this part only if the application requires an adjustable delay timer and a 4.8V detection threshold. Compare against the BD5248G-1 for potential pin-compatible alternatives. Evaluate current consumption specs against system power budgets. Verify compatibility with the required operating temperature range.

Part Context

This component belongs to the ROHM BU43xx series of voltage detectors. It is specifically categorized as a supervisory circuit with adjustable delay capabilities. The device is manufactured using CMOS technology to ensure low standby current. It serves as a replacement or maintenance part for older electronic systems.

Replacement Considerations

The BD5248G-1 is listed as a similar level part with the same pinout and package. Both parts share the 4.8V detection voltage and SSOP-5 form factor. Verify functional equivalence regarding the adjustable delay mechanism before substitution.
