MAX6320PUK46CY+T

Supervisors Overview

The MAX6320PUK46CY+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range up to 5.5 V and features a fixed reset threshold voltage of 4.63 V with an accuracy of 1.5%. The device provides an active low, open-drain reset output and includes a manual reset input. It incorporates a watchdog timer with a 200 ms reset delay time. The component functions in temperatures from -40°C to +125°C, consumes 10 µA of operating current, and is housed in a 5-pin SOT-23 package.

Supervisors Feature Summary

• Integrates watchdog timer functionality for monitoring processor activity alongside power supply supervision.
• Provides manual reset capability via a dedicated input pin for system control flexibility.
• Features an active low, open-drain reset output compatible with various digital logic interfaces.

Supervisors Applications

• Microprocessor (µP) supervisory circuits in digital systems
• Power supply management for embedded controllers
• Watchdog timer implementation in industrial automation

Supervisors Procurement Notes

Verify the specific suffix CY against the official datasheet to confirm the exact threshold voltage and package variant. Confirm RoHS compliance status through manufacturer documentation. Check current availability as distribution channels may list limited stock or end-of-life statuses. Ensure the open-drain output configuration matches your system's pull-up requirements before integration.

Supervisors Selection Notes

Select this component when a fixed 4.63 V threshold is required for single-supply monitoring. The open-drain output necessitates an external pull-up resistor; verify voltage levels match the target logic family. The wide temperature range supports harsh environments. Consider the 10 µA quiescent current for battery-sensitive designs. Validate that the 200 ms timeout aligns with system startup timing constraints.

Supervisors Part Context

This part belongs to the MAX6316–MAX6322 family of 5-pin µP supervisory circuits. These devices combine power supply monitoring with watchdog and manual reset features. The family offers multiple threshold voltages and output configurations. The MAX6320 variant specifically integrates a watchdog timer. All members share the compact SOT-23-5 package for space-constrained applications.

Supervisors Replacement Considerations

Cross-reference with other MAX6320 variants having different threshold voltages if the 4.63 V level is not critical. Verify pinout compatibility with SOT-23-5 packages. Check for equivalent parts from other manufacturers offering similar open-drain outputs and watchdog features.
