MAX6322HPUK46C+T

Supervisors Overview

The MAX6322HPUK46C+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 4.6 V and operates within a supply voltage range up to 5.5 V. It utilizes a SOT-23-5 surface-mount package and supports manual reset functionality with an active high or low push-pull output. The component operates across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Monitors power supply voltages and microprocessor activity for system reliability
• Provides manual reset capability with configurable active high or low push-pull outputs
• Available in factory-trimmed fixed reset threshold voltages for precise supervision

Supervisors Applications

• Microprocessor (μP) supervisory circuits
• Power supply monitoring in digital systems
• System reset generation for embedded controllers

Supervisors Procurement Notes

Verify the specific suffix 'C' against official datasheets to confirm the exact reset threshold voltage and output polarity configuration. Confirm availability status as distribution channels may list limited stock or end-of-life conditions. Ensure the SOT-23-5 package matches the PCB footprint requirements. Cross-reference the manufacturer part number with Analog Devices documentation to validate RoHS compliance and lead-free specifications before procurement.

Supervisors Selection Notes

Select this component when a fixed 4.6 V threshold is required for voltage supervision. Consider the MAX6322 series if manual reset functionality is needed alongside power-on reset. Evaluate the SOT-23-5 package size constraints against available board space. Compare operating temperature ranges to ensure suitability for industrial environments requiring -40°C to +125°C performance. Verify output drive requirements match the connected logic inputs.

Supervisors Part Context

This part belongs to the MAX6316–MAX6322 family of uPower Supervisors. These devices integrate watchdog timers and manual reset features. The MAX6322 variant specifically offers manual reset input capability. The family provides multiple output types including push/pull, open-drain, and bidirectional options. They are designed for low-power applications requiring reliable system reset management.

Supervisors Replacement Considerations

Check the MAX6319 series for similar supervisory functions without watchdog features. Verify compatibility with MAX6322 variants having different threshold voltages if system design allows adjustment. Ensure pinout compatibility with the SOT-23-5 package when substituting.
