MAX6320PUK33BX+T

Supervisors Overview

The MAX6320PUK33BX+T is a microprocessor supervisory circuit from the MAX6316–MAX6322 family, designed to monitor power supplies and processor activity in digital systems. It features a fixed reset threshold voltage of 3.3V with 1.5% accuracy. The device operates within a supply voltage range of 1.63V to 5.5V and consumes only 10µA of quiescent current. It provides a push/pull or open-drain active-low reset output with a 200ms typical timeout period. Integrated watchdog and manual reset inputs enhance system reliability. The component is housed in a compact SOT-23-5 package and supports an extended industrial temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Integrated watchdog timer and manual reset input for comprehensive system monitoring
• Factory-trimmed fixed reset threshold voltage ensuring precise supervision without external components
• Ultra-low quiescent current consumption suitable for battery-powered applications
• Flexible reset output configuration supporting push/pull or open-drain topologies

Supervisors Applications

• Microprocessor power supply monitoring in embedded systems
• Watchdog timer implementation for fault detection in digital controllers
• Manual reset functionality for system recovery in industrial equipment
• Battery-operated devices requiring low standby current supervision

Supervisors Procurement Notes

Verify the specific suffix BX indicates the 3.3V threshold variant against the official datasheet selector guide. Confirm RoHS compliance status and lead times directly with Analog Devices or authorized distributors, as availability may vary. Ensure the SOT-23-5 package dimensions match your PCB footprint requirements before finalizing procurement.

Supervisors Selection Notes

Select this part when a fixed 3.3V reset threshold is required with integrated watchdog capabilities. Compare against other MAX63xx variants if different threshold voltages or output types are needed. Consider the 10µA current draw for power-sensitive designs. Verify that the 200ms timeout meets your system's startup timing constraints.

Supervisors Part Context

This component belongs to the MAX6316–MAX6322 family of 5-pin µP supervisory circuits. These devices offer various combinations of reset outputs, watchdog timers, and manual resets. The MAX6320 specifically includes both watchdog and manual reset features, distinguishing it from simpler supervisor variants within the same series.

Supervisors Replacement Considerations

Compatible substitutes include other MAX6320 variants with different threshold voltages (e.g., MAX6320PUK30A, MAX6320PUK46CY) if voltage levels differ. Cross-reference with MAX6319 or MAX6322 series parts for similar functionality but verify output type and timeout periods match application requirements.
