BD4823G-TR

Overview

The BD4823G-TR is a standard CMOS voltage detector IC from the BD48xxx series, manufactured by Rohm Semiconductor. It features an N-channel open-drain output and provides a fixed detection threshold of 2.3V with ±1% precision. The device operates within a supply voltage range of 0.95V to 10V and supports a reset active state that is low. It includes hysteresis defined as Vs x 0.05 and functions across a temperature range of -40°C to 105°C. The component is housed in a 5-pin SSOP package.

Feature Summary

• High-accuracy voltage monitoring with fixed 2.3V threshold
• Low current consumption suitable for battery-powered applications
• N-channel open-drain output for flexible logic interfacing

Applications

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

Procurement Notes

Verify the specific ordering suffix and package variant when sourcing, as availability may vary. Confirm RoHS compliance status and check for obsolescence notices, as this part may be subject to lifecycle changes. Ensure the supplier provides valid traceability documentation for quality assurance purposes during procurement.

Selection Notes

Select this component for designs requiring a precise 2.3V under-voltage detection point without integrated delay timers. It is suitable for general-purpose supervision where low quiescent current is prioritized. Consider alternative models if adjustable delay or manual reset functionality is required for the specific application design.

Part Context

This component belongs to the BD48xxx series of highly accurate, low-current voltage detectors. The series offers various detection voltages ranging from 2.3V to 6.0V in 0.1V increments. These devices are designed for standard CMOS processes and are commonly used in portable equipment and battery-operated systems.
