BD48E33G-TR

Overview

The BD48E33G-TR is a single-channel voltage detector IC from the Rohm Semiconductor BD48Exx series, designed for precise power supply monitoring. It features an N-channel open-drain output and provides a low-active reset signal triggered at a typical threshold of 3.3V. The device operates within a wide supply voltage range of 0.95V to 10V and maintains high accuracy with a detection voltage precision of ±1%. It supports surface-mount installation in a compact 5-pin SSOP package.

Feature Summary

• High-accuracy voltage detection with ±1% precision tolerance
• Low current consumption suitable for battery-powered applications
• N-channel open-drain output compatible with various logic levels
• Wide operating supply voltage range supporting diverse system architectures

Applications

• Processor supervisor circuits requiring stable voltage monitoring
• Battery backup switching systems for portable electronics
• General-purpose power management supervision in embedded devices

Procurement Notes

Verify component authenticity through authorized distributors due to discontinued status. Confirm RoHS3 compliance and MSL level 1 handling requirements during storage. Check for parameter-equivalent alternatives if new design integration is required, as original stock may be limited.

Selection Notes

Select this component when precise 3.3V monitoring is needed with minimal quiescent current. Ensure compatibility with open-drain output requirements and verify that the 5-SSOP package fits the PCB layout constraints. Consider thermal performance within the -40°C to 105°C operating range for the target application environment.

Part Context

Part of the BD48Exx family of high-precision, low-current voltage detectors. This series offers specific detection voltages in 0.1V increments from 2.3V to 6.0V. The BD48E33G-TR specifically targets 3.3V monitoring applications with enhanced accuracy compared to standard supervisors.

Replacement Considerations

BD4833G-TR, BD5233G-TR, and BD52E33G-TR are listed as parameter-equivalent substitutes by the manufacturer.
