Procurement Notes

Verify the specific suffix G-MTR against the official datasheet to confirm package type and tape-and-reel specifications. Confirm AEC-Q100 compliance requirements for your target application. Check for end-of-life status as this part may be restricted for new designs. Ensure compatibility with existing PCB footprints for the 5-SSOP package before procurement.

Selection Notes

Select this component when precise voltage monitoring with adjustable timing is required in automotive environments. The 2.3V threshold suits low-voltage rail supervision. Consider the CMOS push-pull output for direct logic interfacing. Evaluate the adjustable delay feature against fixed-delay alternatives if timing flexibility is critical for system startup sequences.

Part Context

This part belongs to the BD53Exxx-M family of voltage detectors designed specifically for automotive use. The series offers various threshold voltages while maintaining consistent package and performance characteristics. The BD53E23 variant provides a 2.3V trip point, distinguishing it from other thresholds in the lineup such as 2.5V or 2.8V options.

Replacement Considerations

BD4923G-TR and BD49E23G-MTR are listed as parameter-equivalent substitutes. Verify pinout compatibility and electrical specifications against the original datasheet before substitution.
