MAX6314US31D1-T

Supervisors Overview

The MAX6314US31D1-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 microprocessors like the 68HC11 and includes a debounced manual reset input. The device operates within a supply voltage range up to 5.5 V, with a threshold voltage of 3.08 V and an overvoltage threshold of 3.14 V. It draws 5 uA of operating current and provides a 200 ms reset delay time. Accuracy is specified at 1.8%, and it functions reliably between -40°C and +85°C.

Supervisors Feature Summary

• Bidirectional RESET output allows direct connection to microprocessors with bidirectional reset inputs
• Integrated debounced manual reset input for user-initiated system resets
• Low-power CMOS design suitable for battery-operated applications

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix D1 against official Analog Devices documentation to confirm exact threshold voltage and package variant. Ensure the component matches the required bidirectional output specification for your target microprocessor interface. Confirm RoHS compliance status and lead times through authorized distributors as availability may vary by region.

Supervisors Selection Notes

Select this component when a bidirectional reset interface is required for legacy or specific microprocessor architectures. Compare the 3.08 V threshold against system rail stability requirements. Consider the 5 uA quiescent current for power-sensitive designs. Verify that the SOT-143-4 package fits the PCB layout constraints.

Supervisors Part Context

The MAX6314 belongs to the Maxim Integrated supervisory circuit family, designed for reliable power management in embedded systems. This series eliminates external components by integrating threshold detection and reset timing into a single compact package. The US26/D3 suffix variants indicate different threshold voltages within the same functional family.

Supervisors FAQ

What is the function of the bidirectional RESET output?

The bidirectional RESET output allows the MAX6314 to be directly connected to microprocessors with bidirectional reset pins, such as the 68HC11, simplifying 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 manual reset capability.
