BD48E29G-MTR

Overview

The BD48E29G-MTR is a high-accuracy, ultra-low current voltage detector IC from the BD48Exx series, designed for automotive applications. It features an N-channel open-drain output and detects under-voltage conditions at a typical threshold of 2.9V with ±1% precision. The device operates within a reset active voltage range of 0.95V to 10V and consumes minimal circuit current (0.60µA ON, 0.85µA OFF at Vs=4.8V). Packaged in a compact SSOP-5 format, it supports functional safety analysis and complies with AEC-Q100 standards.

Feature Summary

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

Applications

• Automotive electronic system monitoring
• Processor supervisor circuits
• Under-voltage detection in power management systems

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm package integrity and pin alignment against SSOP-5 specifications. Ensure compatibility with existing PCB footprints and electrical requirements before integration into new designs.

Selection Notes

Select this component for automotive environments requiring precise voltage monitoring with minimal power draw. Consider its open-drain output configuration and lack of manual reset or watchdog features when designing supervision logic. Evaluate thermal performance within the specified operating temperature range.

Part Context

This part belongs to the BD48Exx series of voltage detectors, characterized by high accuracy and low current consumption. It is specifically engineered for automotive use, offering functional safety support. The series provides various detection voltages, with this model set at 2.9V, packaged in SSOP-5 for space-constrained applications.

Replacement Considerations

BD5229G-1 is a recommended replacement with the same SSOP-5 package and 2.9V threshold. Verify parameter differences such as adjustable delay and updated current consumption during substitution.
