MAX6314US31D3-T

Supervisors Overview

The MAX6314US31D3-T 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 fixed threshold of 3.1V and an overvoltage threshold of 3.17V. It draws 5µA of operating current and provides a 200ms reset delay time. The component is housed in a compact SOT-143-4 package and functions reliably across temperatures from -40°C to +85°C.

Supervisors Feature Summary

• Bidirectional RESET output enables direct connection to microprocessors with bidirectional reset inputs
• Debounced manual reset input allows for user-initiated system resets
• Low power consumption suitable for battery-operated applications

Supervisors Applications

• Microprocessor (µP) power supply monitoring
• Digital system supervision
• Systems requiring manual reset functionality

Supervisors Procurement Notes

Verify the specific suffix 'D3' against official Analog Devices documentation to confirm the exact threshold voltage and tolerance specifications. Ensure the package type matches the required PCB footprint. Confirm RoHS compliance status for the specific manufacturing batch if required by regulatory standards. Check availability as distribution may vary.

Supervisors Selection Notes

Select this component when a bidirectional reset interface is required for compatibility with legacy or specific microcontroller architectures. It is suitable for designs needing a manual reset button without external debounce components. Consider the 5µA quiescent current for power-sensitive applications. Verify that the 3.1V threshold aligns with the monitored supply rail requirements.

Supervisors Part Context

The MAX6314 belongs to the Maxim Integrated line of supervisory circuits, specifically engineered for microprocessor reset generation. This series eliminates the need for external components by integrating precise voltage monitoring and timing functions into a small surface-mount package. The MAX6314 variant focuses on bidirectional compatibility, distinguishing it from standard push-pull or open-drain reset outputs found in other family members.

Supervisors FAQ

What is the function of the bidirectional RESET output?

The bidirectional RESET output allows the MAX6314 to be directly connected to microprocessors that have bidirectional reset pins, such as the 68HC11, simplifying the interface design.

Does the MAX6314 include a watchdog timer?

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