MAX6314US30D4

Supervisors Overview

The MAX6314US30D4+T is a low-power CMOS microprocessor supervisory circuit designed to monitor power supplies in µP and digital systems. It features a bidirectional RESET output compatible with processors like the 68HC11, eliminating external components. Key parameters include a 3.0V threshold voltage, 5.5V maximum supply voltage, and 280ms reset delay time. The device operates within a -40°C to +85°C temperature range, consumes 5µA of quiescent current, and is housed in an SOT-143-4 package.

Supervisors Feature Summary

• Bidirectional RESET output for direct connection to microprocessors with bidirectional reset inputs
• Manual reset input capability 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 manual reset functionality

Supervisors Procurement Notes

Verify the specific suffix D4 against official Analog Devices documentation to confirm the exact threshold voltage and tolerance. Ensure the component matches the required bidirectional output configuration for your target microprocessor interface. Confirm RoHS compliance status and packaging type (SOT-143-4) prior to integration into the design.

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 fixed threshold voltage around 3.0V with minimal external component count. Consider the 5µA quiescent current for low-power constraints and the -40°C to +85°C industrial temperature range.

Supervisors Part Context

The MAX6314 belongs to the Maxim Integrated line of microprocessor supervisory circuits. This series focuses on providing reliable power management with minimal external support. The US30 variant specifically targets applications requiring a 3.0V monitoring threshold with bidirectional output capabilities, distinguishing it from open-drain or push-pull variants in the broader family.

Supervisors FAQ

What is the significance of the bidirectional RESET output?

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

Does the MAX6314US30D4 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.
