BD4926G-TR

Overview

The BD4926G-TR is a standard voltage detector IC manufactured by Rohm Semiconductor, designed for monitoring single power supply rails. It features a CMOS output type and operates within a detection voltage range of 0.95V to 10V. The typical under-voltage detection threshold is set at 2.6V with a precision of ±1%. The device supports a reset active state that is low, without manual reset or watchdog timer capabilities. It functions reliably across an extended temperature range from -40°C to +125°C. The component is supplied in a compact SSOP5 package, suitable for surface-mount applications requiring precise voltage supervision.

Feature Summary

• CMOS output interface providing digital signal compatibility
• High accuracy voltage detection with ±1% precision
• Extended industrial operating temperature range capability

Applications

• Processor supervisor circuits
• Battery voltage monitoring systems
• Portable electronic device power management

Procurement Notes

Verify the specific ordering suffix and package variant when sourcing, as availability may vary by region. Confirm RoHS compliance status and environmental declarations prior to integration. Check current lifecycle status, as this part may be designated as not recommended for new designs. Ensure ESD handling protocols are followed during assembly due to the sensitive CMOS input structure inherent to voltage detector ICs.

Selection Notes

Select this component when a fixed 2.6V threshold is required for system supervision. Consider the low standby current characteristics for battery-operated applications. Evaluate the SSOP5 footprint constraints against available PCB real estate. Compare performance metrics against newer family members if long-term supply assurance is critical for the product lifecycle.
