BD5229G-TR

Overview

The BD5229G-TR is a voltage detector from ROHM Semiconductor designed for monitoring single-input power supplies. It features an adjustable reset delay timer and operates within a supply voltage range of 0.95 V to 10 V. The device provides a 3.9 V threshold detection with 1% accuracy and utilizes an open-drain output. Packaged in SSOP-5, it supports surface-mount installation and functions across temperatures from -40°C to +105°C.

Feature Summary

• Adjustable reset delay timer functionality
• Open-drain output configuration
• Single-channel voltage monitoring

Applications

• Power supply supervision
• Microprocessor reset circuits
• Battery-powered system monitoring

Procurement Notes

Verify the Not Recommended for New Designs (NRND) status before integration. Confirm that the specific 3.9V threshold variant matches the target application requirements. Ensure compatibility with the SSOP-5 package dimensions and operating temperature range during final design validation.

Selection Notes

Select this component when a fixed 3.9V detection threshold is required alongside customizable reset timing. The open-drain output allows flexible interfacing with various logic levels. Consider the NRND status for long-term production viability and evaluate alternative models if new design support is critical.

Part Context

This part belongs to the BD52 series of voltage detectors. It shares the SSOP-5 package form factor with other variants in the family but differs in threshold voltage and delay characteristics. The series focuses on low-power supervision for portable and industrial electronics.

Replacement Considerations

BD5229G-1TR is documented as a recommended replacement with the same pinout and package.
