BD48E30G-MTR

Overview

The BD48E30G-MTR is a standard voltage detector designed for automotive applications, classified as Not Recommended for New Designs (NRND). It features a typical detection voltage of 3V with ±1% precision and an open-drain output. The device operates within a reset active voltage range of 0.95 to 10V, consuming 0.60µA in the ON state and 0.85µA in the OFF state at Vs=4.8V. It utilizes Cu wire bonding, complies with AEC-Q100 standards, and functions between -40°C and 105°C.

Feature Summary

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

Applications

• Automotive power supply monitoring
• Battery voltage supervision
• Microprocessor reset circuits in vehicles

Procurement Notes

This component is designated as Not Recommended for New Designs (NRND) by Rohm Semiconductor. Procurement is restricted to supporting existing production lines only; new design integration is prohibited. Verify end-of-life status and lead times carefully, as availability may be limited to existing stock or final time buys. Ensure compatibility with current manufacturing requirements before ordering.

Selection Notes

Select this part only for legacy system maintenance or replacement of existing NRND components. For new projects, consider alternative voltage detectors currently recommended for new designs. Evaluate if the fixed 3V threshold and open-drain output meet specific circuit requirements without needing adjustable delay or manual reset features.

Part Context

Part of the BD48E series, which includes various detection voltages like 2.4V, 3.9V, and 4.6V. These devices share similar packaging (SSOP-5) and functional characteristics, offering high precision and low power consumption for automotive voltage supervision tasks.

Replacement Considerations

BD48E30G-TR is a direct equivalent variant. BD5230G-TR is listed as a parameter-equivalent alternative, though it is obsolete. Check BD52E30G-MTR for adjustable delay options, noting it is also NRND.
