Procurement Notes

Verify the specific datasheet version as this component has been announced for discontinuation (EOL). Confirm availability through authorized distributors, as stock may be limited. Ensure the ordering suffix matches the required tape-and-reel packaging format. Cross-reference pinouts and electrical characteristics with the official Rohm documentation before finalizing procurement decisions.

Selection Notes

Select this component when a single-channel voltage detector with open-drain output is required. It is suitable for applications needing manual reset capability and operation up to 10V. Consider the 5-SSOP package size for space-constrained designs. Verify that the 2.4V threshold meets the system's minimum operating voltage requirements.

Part Context

The BD4724G-TR belongs to the BD47xx series of bipolar voltage detector ICs manufactured by Rohm Semiconductor. This series focuses on providing reliable power management solutions with high accuracy. The part is specifically designed for monitoring single voltage rails in portable and industrial electronics, offering a balance between performance and package efficiency.

Replacement Considerations

Check for direct substitutes within the BD47xx family with compatible thresholds. Verify pin compatibility and output type (open-drain/collector) for other Rohm voltage detectors. Ensure alternative components support the same supply voltage range and manual reset feature if required.
