MAX6314US28D4-T

Supervisors Overview

The MAX6314US28D4-T is a low-power CMOS microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors power supplies in microprocessor and digital systems with a fixed threshold voltage of 2.8V. The device features a bidirectional RESET output compatible with inputs like the 68HC11, a debounced manual reset input, and a typical reset delay time of 200 ms. It operates within an ambient temperature range of -40°C to +85°C and is housed in a surface-mount SOT-143-4 package.

Supervisors Feature Summary

• Bidirectional RESET output for direct connection to microprocessors with bidirectional reset inputs
• Debounced manual reset input for user-initiated system resets
• Low-power CMOS design eliminates external components and adjustments

Supervisors Applications

• Microprocessor (µP) power supply monitoring
• Digital system supervision
• Systems requiring compatibility with 68HC11-style bidirectional reset inputs

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and lead times directly with suppliers, as availability may vary. Ensure the specific suffix matches required electrical parameters before ordering.

Supervisors Selection Notes

Select this part when a fixed 2.8V threshold is required for bidirectional reset interfaces. Consider the SOT-143-4 package for space-constrained surface-mount designs. Verify that the 200 ms timeout meets system stability requirements during power-up sequences.

Supervisors Part Context

This component belongs to the MAX6314 family of µP supervisory circuits designed for reliable power management. The series offers various threshold voltages and package options to suit different microprocessor architectures and system constraints while maintaining low power consumption.

Supervisors Replacement Considerations

Check for other MAX6314 variants with different threshold voltages if the 2.8V level is unsuitable. Verify pinout compatibility with existing PCB layouts when substituting with similar supervisor ICs from other manufacturers.
