MAX6314US46D3+T

Supervisors Overview

The MAX6314US46D3+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 4.63 V and an overvoltage threshold of 4.70 V. It operates within a supply voltage range up to 5.5 V, consumes 5 µA of quiescent current, and provides a reset delay time of 200 ms. Accuracy is specified at 1.8%. The component is housed in a SOT-143-4 package and functions reliably across an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Bidirectional RESET output enables direct connection to microprocessors with bidirectional reset inputs
• Integrated debounced manual reset input for system control
• 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 pinout and electrical characteristics match your design requirements. Confirm RoHS compliance status via the manufacturer's datasheet. Ensure the SOT-143-4 package dimensions align with your PCB footprint constraints before finalizing procurement.

Supervisors Selection Notes

Select this component when a bidirectional reset interface is required for legacy or specific microprocessor architectures. The fixed 4.63 V threshold suits systems where this voltage level represents the critical minimum operating point. Consider the 5 µA current consumption for battery-powered designs. Verify that the 200 ms timeout meets the startup timing requirements of the target logic.
