BD4736G-TR

Overview

The BD4736G-TR is a single-channel voltage detector manufactured by Rohm Semiconductor, designed for supervisory circuit applications. It features an open-drain or open-collector output configuration with a low-active reset signal. The device monitors a specific threshold voltage of 3.6V and operates within a supply voltage range up to 10V. Packaged in a compact 5-pin SSOP (SC-74A/SOT-753) surface-mount format, it supports tape-and-reel delivery. The component functions reliably across an industrial temperature range of -40°C to +75°C.

Feature Summary

• Provides precise voltage monitoring with a fixed 3.6V detection threshold
• Features open-drain/open-collector output compatible with various logic levels
• Delivers active-low reset signal upon undervoltage conditions
• Operates without manual reset or watchdog timer functionality

Applications

• Microprocessor system supervision
• Battery-powered device voltage monitoring
• Embedded controller power management
• Industrial control board reset generation

Procurement Notes

Verify component authenticity through authorized distributors due to discontinued status. Confirm package integrity and pin alignment against the 5-SSOP specification. Check datasheet revisions for any historical parameter updates. Ensure storage conditions maintain moisture sensitivity level 1 compliance prior to assembly.

Selection Notes

Select this component when a fixed 3.6V threshold is required for system reset generation. Consider the open-drain output capability for interfacing with different voltage domains. Evaluate the limited temperature range against environmental requirements. Note that manual reset and watchdog features are absent, necessitating external solutions if those functions are critical.

Part Context

This part belongs to the BD47xx series of standard voltage detectors from Rohm Semiconductor. It shares the same physical footprint and basic operational principles as other members of the family, differing primarily in the specific detection voltage threshold. The series is designed for general-purpose power supply monitoring in consumer and industrial electronics.

Replacement Considerations

BD4736G is the non-tape equivalent. BD5236G-1TR is a recommended replacement with similar package and function but updated specifications.
