MAX6314US43D2+T

Supervisors Overview

The MAX6314US43D2+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 68HC11 and similar microprocessors. The device monitors a single input with a fixed threshold voltage of 4.3V and an overvoltage threshold of 4.37V. It operates within a supply voltage range up to 5.5V, consumes 5µA of quiescent current, and includes a manual reset input. The reset delay time is 200ms, and it 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, such as the 68HC11.
• Integrated debounced manual reset input allows for user-initiated system resets.
• Eliminates external components by providing fixed threshold monitoring and reset timing internally.

Supervisors Applications

• Microprocessor (µP) and digital system power supply monitoring
• Systems requiring compatibility with 68HC11 architecture
• Battery-powered devices requiring low standby current

Supervisors Procurement Notes

Verify the specific suffix D2 against official Analog Devices documentation to confirm the exact threshold voltage variant. Ensure the SOT-143-4 package matches the design footprint. Confirm RoHS compliance status for the specific manufacturing lot if required by regulatory standards. Cross-reference the datasheet revision date to ensure all electrical characteristics align with current specifications.

Supervisors Selection Notes

Select this component when bidirectional interface compatibility with legacy microprocessors like the 68HC11 is required. It is suitable for applications needing a fixed 4.3V threshold with a 200ms timeout. Consider the 5µA quiescent current for power-sensitive designs. Verify that the SOT-143-4 package fits the available PCB space compared to other MAX6314 variants.

Supervisors Part Context

The MAX6314 series consists of low-power CMOS supervisory circuits designed for microprocessor systems. This specific part belongs to the MAX6314 family, which distinguishes itself through its bidirectional output capability. Unlike standard open-drain or push-pull supervisors, this variant supports direct interfacing with complex reset lines found in older microcontroller architectures.

Supervisors FAQ

What is the primary advantage of the bidirectional output?

The bidirectional output allows the MAX6314 to be directly connected to microprocessors with bidirectional reset inputs, such as the 68HC11, without requiring additional level-shifting or buffering components.

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.
