MAX6314US30D4+

Supervisors Overview

The MAX6314US30D4+ 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 voltage with a threshold of 3.0V and an overvoltage threshold of 3.07V. It operates within a supply voltage range up to 5.5V, consumes 5µA of quiescent current, and provides a reset delay time of 280ms. Accuracy is specified at 1.8%. The component functions in the -40°C to +85°C temperature range and is housed in an 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 reset monitoring
• Digital system power supply supervision

Supervisors Procurement Notes

Verify the specific suffix D4 against official Analog Devices documentation to confirm the exact threshold voltage and package variant. Confirm RoHS compliance status for the specific manufacturing lot. Ensure the bidirectional output requirement matches the target microprocessor interface specifications before procurement.

Supervisors Selection Notes

Select this component when interfacing with microprocessors requiring a bidirectional reset signal, such as the 68HC11 family. Choose this part if a fixed 3.0V threshold and 280ms timeout are required. Consider the SOT-143-4 package size constraints and the 5µA current consumption profile for low-power applications.

Supervisors Part Context

The MAX6314 belongs to the Maxim Integrated line of low-power CMOS microprocessor supervisory circuits. This series is engineered to eliminate external components by integrating precise voltage monitoring and manual reset capabilities into a compact surface-mount package, simplifying design for embedded digital systems.

Supervisors FAQ

What is the specific function of the bidirectional output?

The bidirectional output allows the MAX6314 to be directly connected to microprocessors that utilize bidirectional reset pins, 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.
