MAX6320PUK33BX+

Supervisors Overview

The MAX6320PUK33BX+ 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 3.3V, an active-low open-drain reset output, and integrated watchdog timer functionality. It operates within a supply voltage range up to 5.5V and supports manual reset input. The component is housed in a miniature 5-pin SOT-23 package, suitable for surface-mount applications requiring compact board space.

Supervisors Feature Summary

• Integrated configuration enables flexible designs with push/pull, open-drain, and bidirectional reset outputs
• Includes watchdog timer and manual reset features for enhanced system reliability
• Factory-trimmed reset threshold voltages ensure accurate power supply monitoring

Supervisors Applications

• Microprocessor (μP) supervisory circuits in digital systems
• Power supply monitoring for embedded controllers
• Watchdog timer implementation for system stability

Supervisors Procurement Notes

Verify the exact part number suffix against the manufacturer's official documentation to confirm specific electrical parameters such as reset threshold voltage and timeout periods. Ensure compatibility with the target PCB footprint, specifically the 5-pin SOT-23 package. Confirm RoHS compliance status if required by project specifications. Cross-reference with the latest datasheet revision to validate pinout and functional descriptions before procurement.

Supervisors Selection Notes

Select this component when a fixed 3.3V reset threshold is required for power supply supervision. Consider the MAX6320 series for applications needing integrated watchdog and manual reset capabilities. Evaluate the open-drain output type for compatibility with the target logic levels. Verify that the 5-pin SOT-23 package fits the mechanical constraints of the design. Compare alternative threshold voltages within the same family if the 3.3V setting does not match the monitored rail.

Supervisors Part Context

The MAX6320PUK33BX+ belongs to the MAX6316–MAX6322 family of 5-pin μP supervisory circuits. This family provides various combinations of reset outputs and timeout periods. The 'PUK' designation typically indicates a specific reset threshold voltage and output configuration within the Maxim Integrated product line. These devices are designed to monitor power supplies and ensure proper system initialization and operation.

Supervisors Replacement Considerations

Other parts in the MAX6316–MAX6322 family may serve as substitutes if they share the same reset threshold voltage, output type, and package. Verify that any replacement maintains the required watchdog and manual reset functionalities. Check for identical pinout compatibility to ensure direct board swap without redesign.
