BD4856G-TR

Overview

The BD4856G-TR is a standard voltage detector manufactured by ROHM Semiconductor, designed for monitoring single-channel power supply voltages. It features a threshold voltage of 5.6 V with an accuracy of ±1%. The device operates within a supply voltage range of 0.95 V to 10 V and utilizes an open-drain output type. It is housed in a compact SSOP-5 package (SC-74A/SOT-753) suitable for surface mount applications. The component supports a wide operating temperature range from -40°C to +105°C and consumes low static current, making it efficient for battery-powered or energy-sensitive systems.

Feature Summary

• Provides precise under-voltage detection with high accuracy for reliable system supervision
• Features low static current consumption to extend battery life in portable devices
• Utilizes an open-drain output configuration for flexible interfacing with various logic levels

Applications

• Monitoring power supplies in portable electronic devices
• Supervising voltage levels in embedded control systems
• Ensuring stable operation in industrial equipment requiring precise voltage thresholds

Procurement Notes

Verify the specific suffix and package variant when sourcing, as the BD4856 series includes multiple threshold options. Confirm availability status, as this part may be discontinued or subject to last-time buy notices. Ensure compatibility with existing PCB footprints for SSOP-5 packages during replacement planning.

Selection Notes

Select this component when a fixed 5.6 V detection threshold is required for single-channel monitoring. Consider the open-drain output and lack of manual reset if these align with system design constraints. Evaluate the SSOP-5 package size against available board space and thermal requirements for the target application environment.

Part Context

This component belongs to the BD48 series of standard voltage detectors from ROHM Semiconductor. The series offers various threshold voltages to accommodate different supply rail monitoring needs. The BD4856G-TR specifically targets applications requiring a 5.6 V detection point with high precision and low power consumption in a small form factor.

Replacement Considerations

BD5250G-1TR is listed as a recommended substitute with the same SSOP-5 package. Verify threshold voltage differences and reset delay characteristics before implementation.
