MAX6314US29D2+T

Supervisors Overview

The MAX6314US29D2+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 2.93V and an overvoltage threshold of 2.974V. It provides a 200ms reset timeout delay and draws only 5µA of supply current. Accuracy is specified at 1.8%, and it functions reliably between -40°C and +85°C in a compact SOT-143-4 package.

Supervisors Feature Summary

• Bidirectional RESET output enables direct connection to microprocessors with bidirectional reset inputs, such as the 68HC11.

Supervisors Applications

• Microprocessor (µP) system power supply monitoring
• Digital system voltage supervision
• Manual reset input integration

Supervisors Procurement Notes

Verify the specific suffix D2 against official Analog Devices documentation to confirm the exact threshold voltage and tolerance. Ensure the component matches the required bidirectional interface requirements for your target microprocessor. Confirm RoHS compliance status and lead-free specifications via the manufacturer's datasheet before procurement.

Supervisors Selection Notes

Select this component when a bidirectional reset interface is required for compatibility with legacy or specific microprocessor architectures. It is suitable for applications needing a fixed threshold near 2.9V with high accuracy. Consider the 5µA quiescent current for low-power designs and verify that the 200ms timeout meets system startup timing requirements.

Supervisors Part Context

This part belongs to the MAX6314 series of supervisory circuits from Analog Devices/Maxim Integrated. The series is characterized by low power consumption and factory-set thresholds, eliminating the need for external adjustments. The US29 variant specifically targets applications requiring a reset threshold around 2.9V with bidirectional output capability.

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 circuit design.

Does the MAX6314US29D2+T include a watchdog timer?

No, the MAX6314 series does not include a built-in watchdog timer; it functions solely as a voltage supervisor with manual reset capability.
