BD45355G-TR

Overview

The BD45355G-TR is a CMOS voltage detector IC from the BD45 series manufactured by ROHM Semiconductor. It features a fixed detection threshold of 3.5 V with an accuracy of ±1%. The device operates within a supply voltage range of 0.95 V to 10 V and includes a manual reset function. It provides an open-drain output with a fixed delay time of 50 ms. The component is housed in a compact SSOP-5 package and supports surface-mount installation.

Feature Summary

• Provides precise under-voltage monitoring with a fixed 3.5 V threshold and high accuracy.
• Includes a manual reset input for controlled system recovery independent of voltage levels.
• Features a fixed 50 ms reset delay timer to ensure stable power-up sequencing.

Applications

• Processor supervisor circuits requiring reliable voltage monitoring
• Embedded systems needing manual reset capabilities
• Portable devices utilizing low-power supervisory logic

Procurement Notes

Verify current lifecycle status as the part may be discontinued or subject to last-time buy restrictions. Confirm package availability and RoHS compliance details through official ROHM channels before finalizing procurement plans due to potential supply constraints.

Selection Notes

Select this component when a fixed 3.5 V threshold and manual reset functionality are required. Ensure the application supports the 0.95 V to 10 V operating range and utilizes an open-drain output interface compatible with the target logic levels.

Part Context

This part belongs to the BD45 series of voltage detectors, designed for general-purpose supervision tasks. It shares the SSOP-5 package form factor with other variants in the family but differs in threshold voltage and specific feature sets such as manual reset support.

Replacement Considerations

The BD5235G-1 is listed as a recommended replacement with the same SSOP-5 package. Verify functional differences, particularly regarding adjustable versus fixed delay timers and manual reset availability, before substitution.
