• General electronic equipment reset circuits

Procurement Notes

Verify the specific threshold voltage tolerance and package variant against the official datasheet before procurement. Confirm AEC-Q100 qualification status if automotive functional safety analysis is required. Ensure compatibility with the target circuit's input voltage range and output drive requirements. Cross-reference the manufacturer part number with authorized distributor listings to avoid counterfeit components.

Selection Notes

Select this component when overvoltage protection with precise threshold detection is required for CMOS-based systems. The absence of hysteresis ensures the release voltage matches the detection voltage exactly. Consider the CMOS output type for direct interfacing with digital logic inputs. Evaluate the low current consumption benefits for battery-operated or energy-sensitive designs requiring minimal quiescent drain.

Part Context

This part belongs to the BD73Hxx-2C series of Nano Energy™ voltage detectors. It complements the BD70Hxx-xC series which offers Nch open-drain outputs. Both series share similar low-power characteristics but differ in output structure. The series is designed for applications demanding high accuracy and wide operating temperature ranges in compact packages.

Replacement Considerations

BD73H35G-2CTR and BD73H38G-2CTR are compatible alternatives within the same series offering different threshold voltages.
