MAX6314US47D2-T

Supervisors Overview

The MAX6314US47D2-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 of 1.0V to 5.5V, with a fixed threshold voltage of 4.7V. It draws a typical supply current of 5µA and provides a reset timeout period of 280ms. The component is housed in a compact SOT-143-4 package and supports an operating 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 without external components.
• Ultra-low supply current consumption ensures suitability for battery-powered applications.
• Fixed factory-set threshold voltage eliminates the need for external resistor adjustments.

Supervisors Applications

• Microprocessor (µP) and digital system power supply monitoring
• Battery-operated electronic devices requiring low quiescent current
• Systems utilizing 68HC11 or similar bidirectional reset interface controllers

Supervisors Procurement Notes

Verify the specific suffix D2 against official Analog Devices documentation to confirm lead-free status and exact threshold tolerance. Confirm availability through authorized distributors, as stock levels fluctuate. Ensure the SOT-143-4 package matches your PCB footprint requirements before ordering.

Supervisors Selection Notes

Select this component when a bidirectional reset interface is required for compatibility with legacy microcontrollers. Compare the 4.7V threshold against other MAX6314 variants if different voltage levels are needed. Consider the 280ms timeout duration to ensure it aligns with your system's power-up sequence requirements.

Supervisors Part Context

This part belongs to the MAX6314 series of µP reset circuits manufactured by Maxim Integrated, now part of Analog Devices. The series focuses on providing reliable supervision with minimal external component count. The US47 designation indicates the specific 4.7V threshold version within the broader product family.

Supervisors FAQ

Is the MAX6314US47D2-T RoHS compliant?

Yes, the 'D2' suffix typically denotes a lead-free (RoHS compliant) version of the MAX6314 series, whereas non-compliant versions may carry different suffixes.

What is the function of the bidirectional output?

The bidirectional output allows the RESET pin to act as both an output (asserting reset) and an input (accepting reset signals), facilitating direct connection to microprocessors like the 68HC11 that use bidirectional control lines.
