MAX6314US31D3+T

Supervisors Overview

The MAX6314US31D3+T is a low-power CMOS microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.2V to 5.5V and features a fixed threshold voltage of 3.1V for monitoring power supplies. The device provides an active-low, bidirectional reset output compatible with processors such as the 68HC11. It includes a manual reset input and offers a typical reset delay time of 200ms. The component consumes only 5µA of operating supply current and is housed in a compact SOT-143-4 surface-mount package.

Supervisors Feature Summary

• Bidirectional RESET output enables direct connection to microprocessors with bidirectional reset inputs
• Low quiescent current consumption suitable for battery-powered applications
• Manual reset input allows external assertion of the reset signal
• Compact SOT-143-4 package design minimizes board space requirements

Supervisors Applications

• Microprocessor system power supply supervision
• Battery-operated electronic devices requiring low standby current
• Portable equipment with limited power budgets
• Digital systems needing reliable brown-out protection

Supervisors Procurement Notes

Verify the specific suffix D3+T corresponds to the 3.1V threshold variant when ordering. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the SOT-143-4 package footprint matches your PCB layout constraints. Cross-reference the part number with the latest datasheet revision to confirm pinout and electrical characteristics remain unchanged.

Supervisors Selection Notes

Select this component when a bidirectional reset interface is required for compatibility with legacy microcontrollers like the 68HC11. Choose the 3.1V threshold specifically if the target supply rail requires monitoring at that precise voltage level. Consider the 5µA current draw for strict power management scenarios. Verify that the 200ms reset delay meets the timing requirements of the controlled processor during power-up sequences.
