MAX6320PUK26CY-T

Supervisors Overview

The MAX6320PUK26CY-T is a microprocessor supervisory circuit from the MAX6316–MAX6322 family, manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1V to 5.5V and features a fixed reset threshold voltage of 2.63V with 1.5% accuracy. The device provides an active-low open-drain reset output and includes a watchdog timer with a typical timeout period of 1.6s. It supports manual reset functionality and operates in temperatures from -40°C to +125°C.

Supervisors Feature Summary

• Integrated configuration enables flexible designs through factory-trimmed reset thresholds
• Includes watchdog timer and manual reset input for system robustness
• Guarantees reset valid down to minimum supply voltage levels

Supervisors Applications

• Microprocessor power supply monitoring
• Watchdog timer implementation in digital systems
• Manual reset circuit integration

Supervisors Procurement Notes

Verify the specific suffix CY against official datasheets to confirm the exact reset threshold voltage and timeout characteristics. Confirm RoHS compliance status as manufacturing batches may vary. Check current availability as this part number may be subject to limited supply or discontinuation notices from the manufacturer.

Supervisors Selection Notes

Select this component when a fixed low-voltage threshold near 2.63V is required for single-supply monitoring. Ensure the open-drain output type matches the microprocessor reset pin requirements. Verify that the 1.6s watchdog timeout aligns with the system's clock frequency and expected processing cycles.

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 processor activity. The family offers various combinations of reset outputs and timeout periods, packaged in miniature SOT-23-5 form factors for space-constrained applications.

Supervisors Replacement Considerations

Cross-reference with other MAX6320 variants having different threshold suffixes if voltage levels differ. Consider MAX6316–MAX6322 family members with compatible output stages and timeout periods for functional substitution.
