BD48E27G-MTR

Overview

The BD48E27G-MTR is a high-accuracy voltage detector IC from the BD48Exx series, manufactured by ROHM Semiconductor. It features an N-channel open-drain output and supports a detection voltage of 2.7V with ±1% precision. The device operates within a reset active voltage range of 0.95V to 10V and consumes low current (0.60µA ON, 0.85µA OFF at Vs=4.8V). It includes hysteresis voltage defined as Vs x 0.05 and utilizes Cu wire bonding. Packaged in SSOP-5, it is AEC-Q100 qualified for automotive applications but is marked Not Recommended for New Designs.

Feature Summary

• High accuracy voltage detection with ±1% precision
• Low current consumption suitable for power-sensitive designs
• Automotive-grade qualification via AEC-Q100 standard
• Integrated hysteresis to prevent output oscillation

Applications

• Automotive electronic system monitoring
• Microcontroller power supply supervision
• Battery backup switching circuits
• Embedded system reset generation

Procurement Notes

Verify component authenticity through authorized channels due to discontinued status. Confirm RoHS compliance and AEC-Q100 certification requirements for your specific application environment. Check datasheet revisions for any historical updates regarding Cu wire bonding specifications or package dimensions before finalizing procurement documentation.

Selection Notes

This component is designated as Not Recommended for New Designs. Engineers should evaluate replacement options such as the BD5227G-1 or BD5227G-2CGTR which offer similar packages and functions. Consider updated performance metrics like adjustable delay timers or improved output drive capabilities when selecting a successor part for new product development cycles.

Part Context

The BD48E27G-MTR belongs to the BD48Exx family of voltage detectors designed for robust industrial and automotive environments. It provides reliable under-voltage detection with a fixed threshold of 2.7V. The SSOP-5 package allows for compact surface-mount integration. As a legacy automotive-grade part, it supports existing production lines requiring stable voltage supervision without manual reset functionality.

Replacement Considerations

BD5227G-1 and BD5227G-2CGTR are recommended replacements offering compatible SSOP-5 packaging.
