Procurement Notes

Verify the specific suffix G-MTR corresponds to the SSOP-5 tape-and-reel packaging configuration. Confirm AEC-Q100 qualification status for your target automotive grade requirements. Check for end-of-life or not recommended for new design (NRND) status updates from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a precise 2.3V threshold with high accuracy is required for automotive voltage monitoring. The integrated 200ms delay and manual reset capability simplify external circuitry compared to basic detectors. Ensure the operating temperature range meets your application's environmental specifications.

Part Context

This part belongs to the BD46Exxxx-M series of counter timer built-in CMOS voltage detector ICs. These components are specifically engineered for automotive use, offering high accuracy and low current consumption. The series provides various detection voltages to suit different power rail monitoring needs in vehicle electronics.

Replacement Considerations

Check for direct pin-compatible alternatives within the BD46Exxxx-M series with different detection voltages if the 2.3V threshold does not match the target rail. Verify that any substitute maintains the same SSOP-5 package and AEC-Q100 automotive qualification.
