BD48E31G-MTR

Overview

The BD48E31G-MTR is an automotive-grade standard voltage detector manufactured by ROHM Semiconductor. It features a typical under-voltage detection threshold of 3.1 V with ±1% precision. The device operates within a reset active voltage range of 0.95 V to 10 V and utilizes an open-drain output type with a low-active reset state. It consumes 0.60 µA in the ON state and 0.85 µA in the OFF state at Vs=4.8V. The component supports functional safety analysis (FS supportive) and complies with AEC-Q100 standards, operating between -40°C and 105°C.

Feature Summary

• High accuracy detection with ±1% precision
• Ultra-low current consumption for power efficiency
• Automotive grade reliability compliant with AEC-Q100

Applications

• Automotive electronic system monitoring
• Power supply voltage supervision
• Microcontroller reset circuit generation

Procurement Notes

Verify the specific suffix 'MTR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the RoHS compliance status meets environmental regulations for your target market. Ensure the SSOP-5 package dimensions align with your PCB footprint design constraints before finalizing procurement orders.

Selection Notes

Select this component when high precision voltage monitoring is critical for automotive applications requiring low standby power. The open-drain output allows flexible interfacing with various logic levels. Consider the FS supportive classification if functional safety documentation is required for system certification purposes.

Part Context

This part belongs to the BD48E series of standard voltage detectors designed specifically for automotive environments. It is positioned as a legacy or support product for existing designs rather than a new recommendation. The series emphasizes reliability and precision in harsh operating conditions typical of vehicle electronics.

Replacement Considerations

BD48E31G-MTR is marked as Not Recommended for New Designs. Verify availability of alternative parts from the same manufacturer or compatible equivalents that meet the same electrical specifications and package requirements.
