MAX6314US26D3-T

Supervisors Overview

The MAX6314US26D3-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 and an overvoltage threshold of 2.68 V. The device features a bidirectional active-low reset output compatible with inputs such as the 68HC11, along with a debounced manual reset input. 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%, and it functions reliably across a temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Bidirectional RESET output for direct connection to microprocessors with bidirectional reset 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 exact suffix against official documentation, as 'T' typically indicates tape-and-reel packaging while other variants may differ. Confirm RoHS compliance status and lead-free specifications directly with the manufacturer or authorized distributors. Ensure the specific threshold voltage matches the application requirements before procurement.

Supervisors Selection Notes

Select this component when a bidirectional reset interface is required for legacy or specific microprocessor architectures like the 68HC11. It is appropriate for designs needing a fixed 2.63 V threshold with high accuracy and low standby current. Consider the SOT-143-4 package size and operating temperature range constraints during integration.

Supervisors Part Context

This part belongs to the MAX6314 series of supervisory circuits designed for microprocessor reset applications. The series offers various threshold voltages and packages, with the US26 variant specifically targeting the 2.63 V threshold requirement. It is distinct from the MAX6315 series which uses open-drain outputs.
