MAX6314US26D4+T

Supervisors Overview

The MAX6314US26D4+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 microprocessors like the 68HC11. The device monitors a single input with a fixed threshold voltage of 2.63 V and an overvoltage threshold of 2.68 V. It operates within a supply voltage range up to 5.5 V, consumes 5 uA of quiescent current, and provides a reset delay time of 200 ms. Accuracy is specified at 1.8%, and it includes a manual reset input without watchdog or battery backup switching capabilities.

Supervisors Feature Summary

• Bidirectional RESET output for direct connection to microprocessors with bidirectional inputs
• Manual reset input capability for system control
• Low-power operation suitable for battery-supplied systems

Supervisors Applications

• Microprocessor (µP) power supply monitoring
• Digital system supervision
• Systems requiring compatibility with 68HC11 architecture

Supervisors Procurement Notes

Verify the specific suffix D4 against official Analog Devices documentation to confirm pinout and electrical characteristics match the D3 variant, as suffixes often indicate package or temperature grade differences. Ensure the component is RoHS compliant if required by your manufacturing standards. Cross-reference the manufacturer's latest datasheet revision to confirm availability and any potential obsolescence notices before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a bidirectional reset interface is required for legacy or specific microprocessor architectures. It is appropriate for applications needing a fixed 2.63 V threshold with high accuracy. Consider the SOT-143-4 package constraints and the 200 ms timeout period relative to system startup requirements. Verify that the 5 uA current consumption meets the power budget for the intended operational mode.

Supervisors Part Context

This part belongs to the MAX6314 series of µP reset circuits from Maxim Integrated, now part of Analog Devices. The series focuses on providing reliable power supervision with minimal external components. The US26 designation typically indicates the specific threshold voltage and package type within the broader family of supervisory ICs designed for general-purpose digital logic protection.

Supervisors FAQ

What is the function of the bidirectional RESET output?

The bidirectional output allows the MAX6314 to be directly connected to microprocessors with bidirectional reset pins, such as the 68HC11, facilitating seamless integration without additional level-shifting components.

Does the MAX6314US26D4+T include a watchdog timer?

No, the MAX6314 series does not include a built-in watchdog timer; it functions solely as a voltage supervisor with a manual reset input.
