BD5326G-TR

Overview

The BD5326G-TR is a voltage detector from the ROHM Semiconductor BD53 series, designed for monitoring single-input power supply lines. It features a fixed threshold voltage of 2.6 V with a precision accuracy of ±1%. The device utilizes a CMOS output type and incorporates a programmable reset delay timer to manage signal timing during power transitions. It operates within a wide supply voltage range up to 10 V and supports surface-mount installation in an SSOP-5 package. The component functions across an industrial temperature range from -40°C to +105°C.

Feature Summary

• CMOS output interface for digital logic compatibility
• Programmable reset delay timer functionality
• High detection accuracy with ±1% threshold precision

Applications

• Portable electronic devices requiring low-power supervision
• Battery-operated systems needing under-voltage protection
• Embedded controllers requiring stable power-on reset signals

Procurement Notes

Verify current availability status as the component may be discontinued or subject to last-time-buy restrictions. Confirm package integrity and RoHS compliance documentation prior to integration. Ensure design-in approval aligns with manufacturer lifecycle notices to mitigate long-term supply risks.

Selection Notes

Select this part when a fixed 2.6 V threshold with high precision is required alongside adjustable reset timing. Compare against the BD5226G-1 if open-drain outputs or automotive qualification are needed instead of CMOS outputs. Verify that the SSOP-5 footprint matches the target PCB layout constraints.

Part Context

This component belongs to the BD53 series of supervisory circuits manufactured by ROHM Semiconductor. It serves as a specialized voltage detector within the PMIC category, focusing on precise under-voltage monitoring without manual reset or watchdog capabilities. The series targets cost-sensitive consumer and industrial applications requiring reliable power management.

Replacement Considerations

The BD5226G-1 is documented as a similar level replacement with the same pinout and package. Note that the substitute offers an open-drain output rather than CMOS and has different electrical characteristics.
