MAX6314US44D3-T

Supervisors Overview

The MAX6314US44D3-T is a low-power CMOS microprocessor supervisory circuit designed to monitor power supplies in microprocessor and digital systems. It features a bidirectional RESET output compatible with inputs such as the 68HC11. The device operates within a supply voltage range of 2.7V to 5.5V, with a fixed threshold voltage of 4.4V. It provides a reset pulse duration of 200ms and draws only 10µA of supply current. Packaged in a compact SOT-143-4 surface-mount case, it eliminates the need for external components.

Supervisors Feature Summary

• Bidirectional RESET output allows direct connection to microprocessors with bidirectional reset inputs
• Low-power operation with 10µA supply current consumption
• Fixed 4.4V threshold voltage ensures reliable monitoring
• Compact SOT-143-4 surface-mount package

Supervisors Applications

• Microprocessor system power supply monitoring
• Digital system voltage supervision
• Battery-powered devices requiring low quiescent current
• Embedded controllers needing manual reset capability

Supervisors Procurement Notes

Verify the exact suffix D3 against official Analog Devices documentation to confirm pinout and electrical specifications. Confirm RoHS compliance status for the specific manufacturing batch. Check lead-free availability if required by assembly standards. Ensure the SOT-143-4 footprint matches the design layout. Validate operating temperature range requirements against the datasheet specifications.

Supervisors Selection Notes

Select this component when a bidirectional reset interface is required for compatibility with legacy microcontrollers like the 68HC11 family. Choose based on the fixed 4.4V threshold if the target supply voltage is stable at 5V. Consider the 200ms delay for systems tolerant of longer startup times. Evaluate the SOT-143-4 package size constraints against available board space.

Supervisors Part Context

The MAX6314 belongs to Maxim Integrated's uP Reset Circuit family, designed for simple, cost-effective power supervision. This series typically offers fixed thresholds and manual reset options. The US44 variant specifically targets 5V systems with a 4.4V trip point. The D3 suffix indicates the SOT-143-4 package configuration.

Supervisors FAQ

What is the function of the bidirectional RESET output?

The bidirectional output allows the MAX6314 to drive or accept reset signals, enabling direct interfacing with microprocessors that have bidirectional reset pins, such as the 68HC11.

Does the MAX6314US44D3-T include a watchdog timer?

No, the standard MAX6314 does not include a watchdog timer. It provides basic voltage supervision and manual reset functionality only.
