Supervisors Procurement Notes

Verify the specific suffix D3 against official datasheets to confirm the 4.80V threshold variant. Confirm lead-free status and RoHS compliance through manufacturer documentation. Check for obsolescence notices as some MAX6315 variants face end-of-life status. Ensure the SOT-143-4 package matches your PCB footprint requirements before procurement.

Supervisors Selection Notes

Select this part when a fixed 4.80V threshold is required for single-channel supervision. Compare against other MAX6315 variants with different voltage thresholds if system requirements change. Consider the open-drain output compatibility with your logic levels. Verify that the 200ms delay meets your system startup timing constraints.

Supervisors Part Context

This component belongs to the MAX6315 series of supervisory circuits. It is designed for applications requiring simple, low-cost power monitoring. The series offers various threshold voltages packaged in compact SOT-143 formats. It serves as a fundamental building block for ensuring stable operation in embedded systems.

Supervisors Replacement Considerations

Check for direct pin-compatible substitutes within the MAX6315 family with adjusted threshold voltages. Verify equivalent performance from other manufacturers offering similar open-drain reset ICs in SOT-143 packages.
