MAX6314US26D2

Supervisors Overview

The MAX6314US26D2 is a low-power CMOS microprocessor supervisory circuit designed to monitor power supplies in digital systems. It features a bidirectional RESET output compatible with processors like the 68HC11 and includes a debounced manual reset input. The device operates within a supply voltage range up to 5.5V, with a specific threshold of 2.6V for this variant. It provides a fixed reset timeout period of 280ms and draws only 5µA of quiescent current. The component is housed in a compact SOT-143-4 surface-mount package and functions reliably across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Bidirectional RESET output enables direct connection to microprocessors with bidirectional reset inputs
• Integrated debounced manual reset input allows for user-initiated system resets
• Low quiescent current consumption supports battery-powered applications
• Eliminates external components by integrating monitoring and reset timing functions

Supervisors Applications

• Microprocessor (µP) power supply monitoring
• Digital system voltage supervision
• Systems requiring bidirectional reset compatibility

Supervisors Procurement Notes

Verify the exact suffix D2 against official Analog Devices documentation to confirm the specific threshold voltage and package details, as suffixes define electrical characteristics. Ensure the source document explicitly lists the MAX6314US26D2 part number rather than generic family members. Cross-reference the manufacturer's latest datasheet revision to confirm availability status and any potential obsolescence notices before procurement planning.

Supervisors Selection Notes

Select this component when a bidirectional reset interface is required for legacy or specific microcontroller architectures. The fixed 2.6V threshold suits 3.3V logic systems where precise brown-out detection is needed. Consider the SOT-143-4 package for space-constrained designs. Verify that the 280ms timeout meets the target processor's startup requirements without additional external timing components.

Supervisors Part Context

The MAX6314 belongs to Maxim Integrated's line of low-power µP supervisory circuits. This series focuses on simplifying design by integrating reset generation and monitoring into a single small package. The US26 designation typically indicates a specific voltage threshold variant within the broader MAX6314 family, tailored for standard 3.3V operation scenarios common in embedded digital systems.

Supervisors FAQ

What is the function of the bidirectional RESET output?

The bidirectional output allows the MAX6314 to drive the reset pin of microprocessors that have bidirectional I/O pins, such as the 68HC11, eliminating the need for level shifting or additional buffering.

Does the MAX6314 include a watchdog timer?

No, the standard MAX6314 does not include a watchdog timer; it functions solely as a voltage supervisor with a manual reset input.
