MAX6314US25D1-T

Supervisors Overview

The MAX6314US25D1-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 devices like the 68HC11, eliminating external components. The device provides manual reset input functionality and operates within a supply voltage range of 1V to 5.5V. Key electrical parameters include a threshold voltage of 2.50V, an overvoltage threshold of 2.57V, and a reset delay time of 200ms. It draws only 5µA of operating current and offers 1.8% accuracy. The component is available in SOT-143-4 packages and supports industrial temperature ranges.

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 minimizing standby current consumption
• Integrated debouncing and timeout functions to ensure reliable operation

Supervisors Applications

• Microprocessor (µP) power supply monitoring
• Digital system voltage supervision
• Systems requiring manual reset functionality
• Battery-powered applications due to low quiescent current

Supervisors Procurement Notes

Verify the specific suffix 'D1' against official Analog Devices documentation to confirm the exact threshold voltage and package variant, as suffixes define critical electrical characteristics. Ensure compatibility with bidirectional reset requirements if interfacing with legacy microcontrollers. Confirm RoHS compliance status through the manufacturer's latest datasheet or ordering guide, as '+T' variants typically indicate lead-free packaging but require validation for specific regional regulations.

Supervisors Selection Notes

Select this component when a bidirectional reset interface is required for microprocessors such as the 68HC11 family. Choose based on the precise 2.50V threshold requirement and the need for manual reset integration. Consider the 5µA current draw for battery-sensitive designs. Verify that the SOT-143-4 package fits the PCB layout constraints. Ensure the 200ms timeout meets the system's power-up stability requirements without excessive delay.

Supervisors Part Context

The MAX6314 belongs to the Maxim Integrated (now Analog Devices) line of low-power microprocessor supervisory circuits. This series is engineered to replace discrete resistor-capacitor networks and comparators, simplifying board design. The MAX6314 specifically targets applications needing bidirectional reset compatibility, distinguishing it from standard open-drain or push-pull reset ICs in the broader MAX63xx portfolio.

Supervisors Replacement Considerations

Direct substitutes within the same family include MAX6314US25D1+T (lead-free version). Other threshold variants like MAX6314US26D3+T or MAX6314US33D1-T offer different trip points but share identical pinouts and bidirectional functionality. Cross-reference with MAX6315 series if open-drain output is acceptable instead of bidirectional.
