Supervisors Applications

• Microprocessor (μP) supervisory circuits
• Power supply management in digital systems
• Battery backup systems requiring voltage monitoring

Supervisors Procurement Notes

Verify the specific suffix 'CY' against official datasheets to confirm package and temperature grade details, as suffixes often denote manufacturing lot or packaging variations rather than functional changes. Confirm availability status directly with authorized distributors, as this part may be subject to limited supply or special order constraints. Ensure compatibility with existing board layouts using the SOT-23-5 package dimensions.

Supervisors Selection Notes

Select this component when a fixed 4.6V reset threshold is required for single-input voltage monitoring. Consider the manual reset feature if external hardware reset capability is necessary. Evaluate the 1.4ms reset delay against system startup timing requirements. Verify that the SOT-23-5 package fits the design constraints and that the industrial temperature range meets environmental specifications.

Supervisors Part Context

This part belongs to the MAX6316–MAX6322 family of 5-pin μP supervisory circuits. These devices are designed to monitor power supplies and ensure reliable system operation by detecting under-voltage conditions. The family offers various combinations of reset outputs and features like watchdog timers and manual resets, providing flexibility for different embedded system architectures.

Supervisors Replacement Considerations

Direct substitutes within the MAX6316–MAX6322 family include parts with identical 4.6V thresholds and similar package configurations, such as MAX6318MHUK46BZ+T or MAX6319MHUK46C+T, provided the specific suffix variations match the required packaging and temperature ratings.

Supervisors FAQ
