BD4932G-TR

Overview

The BD4932G-TR is a CMOS voltage detector IC from the ROHM BD49 series, housed in an SSOP-5 package. It features a typical under-voltage detection threshold of 3.2 V with ±1% accuracy and a fixed reset delay time of 100 µs. The device operates within a supply voltage range up to 10 V and supports an operating temperature range from -40°C to +105°C. It provides a single input for monitoring without manual reset or watchdog timer capabilities.

Feature Summary

• CMOS output interface for direct logic integration
• High precision voltage detection with ±1% tolerance
• Ultra-low current consumption for power efficiency

Applications

• Microcontroller system reset circuits
• Logic circuit power supervision
• Battery-powered device voltage monitoring

Procurement Notes

Verify component authenticity through authorized channels as this part is marked as obsolete by the manufacturer. Confirm RoHS compliance status via official datasheets before procurement. Check for availability of end-of-life inventory from licensed distributors. Ensure storage conditions meet semiconductor handling standards to prevent degradation.

Selection Notes

Select this component when a precise 3.2 V threshold is required for CMOS-based systems. Consider the SSOP-5 package constraints for PCB layout. Evaluate thermal performance within the specified -40°C to +105°C range. Compare against similar BD49 series variants if different voltage thresholds are needed.

Part Context

Part of the BD49xxx series of standard CMOS voltage detectors designed for low-current applications. The series offers various detection voltages from 2.3V to 6.0V in 0.1V increments. This specific model targets applications requiring stable reset signals for digital logic powered by single-supply sources.
