BD4924G-TR

Overview

The BD4924G-TR is a standard CMOS voltage detector IC manufactured by ROHM Semiconductor. It operates within a supply voltage range of 0.95V to 10V and features a typical under-voltage detection threshold of 2.4V with ±1% precision. The device provides a low-active CMOS output without manual reset or watchdog timer functions. It is housed in an SSOP-5 package, supports a minimum packing quantity of 3000 units in tape-and-reel packaging, and complies with RoHS standards. The component is designated as Not Recommended for New Designs (NRND).

Feature Summary

• CMOS output interface with low-active state signaling.
• High detection accuracy with ±1% voltage precision.
• Low power consumption suitable for battery-operated applications.

Applications

• Microprocessor power supply monitoring.
• Portable battery-powered equipment supervision.
• Multi-output power system oversight.

Procurement Notes

Verify the current lifecycle status before procurement, as this component is marked Not Recommended for New Designs. Confirm availability through authorized distributors, noting that stock levels may be limited due to end-of-life designation. Ensure compatibility with existing designs rather than initiating new projects. Check for specific ordering suffixes if required by legacy systems.

Selection Notes

Select this component only for maintaining existing hardware where the SSOP-5 package and 2.4V threshold are fixed requirements. Consider the NRND status when planning long-term production runs. Evaluate alternative devices from the same family if future scalability is needed. Verify that the CMOS output drive capability meets the load requirements of the downstream circuitry.

Part Context

This part belongs to the BD49xx series of standard voltage detectors from ROHM Semiconductor. The series is characterized by high accuracy and low current consumption. The BD4924G-TR specifically targets applications requiring precise voltage supervision in compact surface-mount packages. It serves as a critical component for ensuring system stability during power fluctuations.

Replacement Considerations

The BD5224G-1 is listed as a recommended replacement with the same SSOP-5 package. Note differences in output type (Open Drain vs. CMOS) and reset delay capabilities when substituting.
