BD46355G-TR

Overview

The BD46355G-TR is a single-channel voltage detector manufactured by Rohm Semiconductor, designed for supervisory circuit applications. It features a fixed threshold voltage of 3.5V with high precision monitoring capabilities. The device utilizes a push-pull/totem pole output configuration and provides an active-low reset signal. A minimum reset delay time of 45ms ensures stable system recovery during power transitions. Operating within a wide temperature range from -40°C to 105°C, it supports surface-mount installation in a compact 5-SSOP package.

Feature Summary

• Monitors a single voltage channel with a precise 3.5V detection threshold
• Generates an active-low reset signal using a push-pull output stage
• Incorporates a fixed minimum reset delay timer to prevent false triggering

Applications

• Power supply supervision in embedded systems
• Microcontroller reset circuitry
• Battery-operated device voltage monitoring

Procurement Notes

Verify the component status as discontinued or last-time-buy through official manufacturer channels before finalizing procurement plans. Confirm that the 5-SSOP package and reel packaging specifications align with existing assembly processes. Ensure compatibility with RoHS3 standards and check for any specific handling requirements associated with end-of-life inventory management.

Selection Notes

Select this component when a fixed 3.5V threshold with a guaranteed minimum delay is required for reliable system resets. The push-pull output offers stronger drive capability compared to open-drain alternatives. Consider the operating temperature range and package size constraints against available space on the printed circuit board layout.

Part Context

This part belongs to the BD46xxx series of voltage detectors from Rohm Semiconductor. It serves as a specialized integrated circuit for power management, providing essential supervision functions. The TR suffix indicates tape-and-reel packaging suitable for automated surface-mount technology assembly lines.

Replacement Considerations

The BD5235G-1 is documented as a similar level replacement with the same package type. Verify electrical parameter alignment and supply status before substitution.
