MAX6314US26D1+T

Supervisors Overview

The MAX6314US26D1+T is a low-power CMOS microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors power supplies in microprocessor and digital systems with a fixed threshold voltage of 2.63 V. The device features an active-low, bidirectional reset output compatible with inputs such as the 68HC11. It includes a debounced manual reset input and provides a reset timeout period of 200 ms after the supply voltage rises above the threshold. Operating from 1.2 V to 5.5 V, it draws only 5 µA of supply current. Accuracy is specified at 1.8%, with an operating temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Bidirectional reset output allows direct connection to microprocessors with bidirectional reset inputs, eliminating external components.
• Integrated debounced manual reset input ensures reliable system initialization upon user command.
• Low quiescent current consumption supports battery-operated applications requiring extended standby life.

Supervisors Applications

• Microprocessor reset circuits for embedded systems
• Power supply monitoring in digital control systems
• Battery-powered devices requiring low standby current

Supervisors Procurement Notes

Verify the specific suffix D1 against official Analog Devices documentation to confirm the exact threshold voltage variant, as the MAX6314 series offers multiple fixed thresholds. Confirm RoHS compliance status and package availability through authorized distributors. Check for obsolescence notices or lifecycle status directly from the manufacturer before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a bidirectional reset interface is required for compatibility with legacy microcontrollers like the 68HC11 family. Ensure the 2.63 V threshold aligns with the target system's minimum operating voltage. Consider the SOT-143-4 package constraints for PCB layout. Verify that the 200 ms delay meets the system's startup timing requirements.

Supervisors Part Context

The MAX6314 belongs to Maxim Integrated's line of low-power CMOS supervisory circuits designed for microprocessor systems. This series focuses on providing reliable reset generation without external adjustments. The US26 designation indicates a specific threshold voltage within the broader MAX6314 product family, which includes variants for different voltage rails.

Supervisors Replacement Considerations

Direct pin-compatible replacements within the same series include other MAX6314 variants with different threshold voltages if the 2.63 V requirement can be adjusted. Cross-reference with MAX6315 series for similar functionality but note potential differences in output type or accuracy specifications.
