MAX6320PUK30DZ+T

Supervisors Overview

The MAX6320PUK30DZ+T is a microprocessor supervisory circuit from the MAX6316–MAX6322 family, manufactured by Analog Devices Inc./Maxim Integrated. It monitors power supplies and processor activity in digital systems. The device features a fixed reset threshold voltage of 3V with an accuracy of 1.5%. It provides a minimum power-on reset timeout period of 1.12 seconds and includes a watchdog timer with selectable timeout periods ranging from 6.3ms to 25.6s. The output is available as active low open drain or open collector. It operates within a supply voltage range up to 5.5V and functions across a temperature range of -40°C to +125°C.

Supervisors Feature Summary

• Integrated configuration supports flexible designs with multiple reset output types including push/pull, open-drain, and bidirectional options.

Supervisors Applications

• Monitoring power supplies in digital systems
• Supervising microprocessor activity
• Ensuring system reliability through watchdog timer functionality

Supervisors Procurement Notes

Verify the specific suffix codes (PUK30DZ+T) against the official Analog Devices datasheet to confirm the exact reset threshold, timeout period, and package variant. Ensure compatibility with the target application's voltage levels and thermal requirements before procurement.

Supervisors Selection Notes

Select this component when a fixed 3V threshold and integrated watchdog timer are required for system supervision. Consider the SOT-23-5 package size for space-constrained designs. Verify that the 1.12s minimum timeout meets the system startup requirements.

Supervisors Part Context

This part belongs to the MAX6316–MAX6322 family of 5-pin μP supervisory circuits. These devices offer various combinations of reset outputs and features like manual reset and watchdog timers. The MAX6320 variant specifically includes the watchdog feature alongside the power-on reset function.

Supervisors Replacement Considerations

Other parts in the MAX6316–MAX6322 family may serve as substitutes if different thresholds or timeout periods are needed. Verify pinout and electrical characteristics match the original design requirements.
