MAX6314US31D3+

Supervisors Overview

The MAX6314US31D3+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 processors like the 68HC11, eliminating external components. The device includes a debounced manual reset input and asserts a reset signal when the supply voltage falls below a preset threshold or upon manual assertion. Key parameters include a 5.5V maximum supply voltage, 280ms reset delay, 5uA operating current, and operation within a -40°C to +85°C temperature range.

Supervisors Feature Summary

• Bidirectional RESET output for direct connection to microprocessors with bidirectional inputs
• Debounced manual reset input for user-initiated system resets
• Low-power CMOS design suitable for portable applications

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix 'D3+' against official Analog Devices documentation to confirm the exact threshold voltage and package variant. Ensure the part number matches the required reset threshold for your application. Confirm RoHS compliance status as indicated in the datasheet. Check availability through authorized distributors, as stock levels may vary.

Supervisors Selection Notes

Select this component when a bidirectional reset interface is required for specific microcontrollers. Consider the 280ms timeout period and fixed threshold voltage. Evaluate the SOT-143-4 package size constraints. Compare against other MAX6314 variants if different thresholds or active-low outputs are needed.

Supervisors Part Context

Part of the MAX6314 series from Maxim Integrated, now part of Analog Devices. This family focuses on simple, reliable power supervision without complex programming. The US31D3+ variant specifically targets the 3.1V threshold requirement within the standard industrial temperature range.

Supervisors Replacement Considerations

Check for MAX6314US31D3+T or other suffixes within the MAX6314 family for pin-compatible alternatives with different thresholds.
