MAX6314US31D4+

Supervisors Overview

The MAX6314US31D4+T is a low-power CMOS microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 2.0V to 5.5V and features a fixed reset threshold voltage of 3.1V. The device provides a bidirectional active-low RESET output compatible with microprocessors such as the 68HC11. It includes a debounced manual reset input and offers a typical reset timeout period of 280ms. The component functions in an industrial temperature range from -40°C to +85°C and is available in a compact SOT-143-4 surface-mount package.

Supervisors Feature Summary

• Bidirectional RESET output enables direct connection to microprocessors with bidirectional reset inputs, eliminating the need for external level-shifting components.

Supervisors Applications

• Microprocessor power supply monitoring in digital systems
• Battery-powered equipment requiring low quiescent current
• Embedded controllers needing manual reset functionality

Supervisors Procurement Notes

Verify the specific suffix 'D4+' against official Analog Devices documentation to confirm the exact threshold voltage and package variant. Ensure the order quantity matches distributor reel or cut-tape specifications. Confirm RoHS compliance status and lead times directly with authorized suppliers prior to procurement.

Supervisors Selection Notes

Select this component when a bidirectional interface is required for legacy or specific microprocessor architectures like the 68HC11 family. Choose this part over push-pull variants if the target system utilizes open-drain or tri-state reset lines. Verify that the 3.1V threshold aligns with the minimum operating voltage of the monitored circuit.

Supervisors Part Context

The MAX6314 belongs to the Maxim Integrated supervisory circuit family designed for reliable power management. This series focuses on providing essential reset generation without complex external adjustments. The US31D4+ designation indicates a specific threshold voltage configuration within the broader MAX6314 product line.

Supervisors Replacement Considerations

Cross-reference with MAX6314US31D3+T for identical electrical characteristics in alternative packaging. Check MAX6314US31D2+T for pin-compatible options with different manufacturing revisions. Verify availability of MAX6314US31D1-T if lead time constraints require tape-and-reel alternatives.
