BD53E30G-MTR

Overview

The BD53E30G-MTR is a CMOS output voltage detector manufactured by ROHM Semiconductor, designed for automotive applications. It features a typical under-voltage detection threshold of 3 V with ±1% precision and an adjustable reset delay timer controlled by an external capacitor. The device operates within a supply voltage range of 0.95 to 10 V and supports a low active reset state without manual reset or watchdog functions. It is housed in a compact SSOP-5 package, suitable for surface-mount installation.

Feature Summary

• Adjustable reset delay timer functionality enabled by external capacitor connection
• High accuracy voltage detection with ±1% precision for reliable monitoring
• Automotive-grade qualification compliant with AEC-Q100 standards

Applications

• Automotive electronic control unit power supervision
• Battery voltage monitoring systems
• Microprocessor reset circuit generation

Procurement Notes

Verify the specific suffix 'MTR' indicates tape-and-reel packaging configuration. Confirm RoHS compliance status and functional safety classification as FS supportive. Check current lifecycle status as Not Recommended for New Designs (NRND) to assess long-term availability risks for production planning.

Selection Notes

Select this component when a precise 3 V threshold with high accuracy is required for automotive environments. Ensure the design accommodates the adjustable delay feature via external capacitance. Verify compatibility with the SSOP-5 footprint and confirm that the CMOS output drive capability meets load requirements.

Part Context

This part belongs to the BD53ExxG series of delay-time variable voltage detectors. It shares pinout and package dimensions with other variants in the family, differing primarily in detection voltage thresholds. The series is characterized by low current consumption and robust performance in automotive temperature ranges.

Replacement Considerations

BD53E30G-TR offers identical electrical specifications and pinout in a standard reel format. BD5230G-1 provides similar functionality but may differ in output type or precision characteristics; verify datasheet alignment before substitution.
