MAX6320PUK45CY+T

Supervisors Overview

The MAX6320PUK45CY+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.8 V to 5.5 V and features a fixed reset threshold voltage of 4.5 V. The device provides an active-low, open-drain reset output with a typical delay time of 200 ms. It includes manual reset functionality and a watchdog timer. The component is housed in a 5-pin SOT-23 package and supports surface-mount installation. It functions reliably across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Integrated watchdog timer for monitoring processor activity

Supervisors Procurement Notes

Verify the specific suffix CY against official documentation to confirm the exact reset threshold voltage and tolerance. Ensure the ordering code matches the required package type and temperature grade. Confirm RoHS compliance status through the manufacturer's current certification records before finalizing procurement specifications.

Supervisors Selection Notes

Select this component when a fixed 4.5V threshold is required for systems operating at 5V logic levels. Consider the open-drain output requirement for pull-up resistor integration. Evaluate the need for manual reset and watchdog features against system complexity. Verify that the SOT-23-5 package fits the available PCB footprint constraints.

Supervisors Part Context

This part belongs to the MAX6316–MAX6322 family of 5-pin μP supervisory circuits. These devices are designed to monitor power supplies and ensure reliable system operation by providing reset signals based on voltage thresholds. The family offers various combinations of reset outputs, timeout periods, and threshold voltages to suit different digital system requirements.

Supervisors Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Cross-reference with other MAX6320 variants only if the reset threshold and package match exactly.
