Procurement Notes

Verify component authenticity through authorized distributors due to potential obsolescence status. Confirm package integrity and RoHS compliance upon receipt. Cross-reference the full part number including suffixes to ensure exact electrical parameter matching. Check manufacturer announcements for end-of-life notices or recommended replacement alternatives before finalizing procurement plans.

Selection Notes

Select this component when a fixed 4.40V threshold is required for systems operating between 2.4V and 5.5V. The integrated battery backup feature makes it suitable for applications where uninterrupted supervision is critical during power switches. Ensure the SOT-23-6 footprint aligns with the PCB design constraints and that the active-high output logic matches the target controller requirements.

Part Context

This part belongs to the MAX6361 series of low-power MPU supervisors from Maxim Integrated. The series offers various fixed threshold voltages and packaging options to accommodate different system voltage levels and space constraints. These circuits are designed to replace discrete supervisor solutions, reducing board space and component count while providing reliable reset generation for embedded systems.

Replacement Considerations

Consult official documentation for direct pin-compatible substitutes within the MAX6361 family. Verify that alternative parts match the 4.40V threshold and battery backup functionality. Consider newer generations from Analog Devices if long-term availability is a concern.
