Supervisors Procurement Notes

Verify the exact suffix D1 against official Analog Devices documentation to confirm the specific timeout period and pinout configuration. Ensure the sourcing channel provides genuine Maxim Integrated or Analog Devices products to avoid counterfeit components. Check RoHS compliance status if required by your manufacturing standards. Confirm availability through authorized distributors as lead times may vary.

Supervisors Selection Notes

Select this part when interfacing with microprocessors requiring bidirectional reset signals, such as the 68HC11 family. Choose the US44 variant specifically for applications requiring a 4.4V reset threshold. Consider the 5µA supply current for battery-operated designs. Verify that the SOT-143 package fits your PCB layout constraints and thermal requirements.

Supervisors Part Context

This component belongs to the MAX6314 series of supervisory circuits from Maxim Integrated, now part of Analog Devices. The series is known for providing reliable power management solutions with minimal external component requirements. The MAX6314 family offers various threshold voltages and timeout periods to suit different system architectures.

Supervisors Replacement Considerations

Check for pin-compatible alternatives within the MAX6314 series with different threshold voltages if system requirements change. Verify functional equivalence with MAX811 devices if legacy compatibility is needed.
