MAX6321HPUK26CY+

Supervisors Overview

The MAX6321HPUK26CY+ is a microprocessor supervisory circuit in a 5-pin SOT-23 package. It monitors power supplies with a reset threshold voltage of 2.63V (min 2.591V, max 2.669V). Operating from 1V to 5.5V, it features a watchdog timer and manual reset input. The device draws 10µA typical supply current and offers active high/low, open drain, or push-pull outputs. It operates between -40°C and +125°C with a typical reset timeout of 200ms.

Supervisors Feature Summary

• Integrated watchdog timer for monitoring processor activity
• Manual reset input capability for system control
• Configurable output drivers including push-pull and open-drain options

Supervisors Applications

• Microprocessor power supply supervision
• Battery-powered systems requiring low quiescent current
• Embedded controllers needing watchdog functionality

Supervisors Procurement Notes

Verify the specific suffix CY against official Analog Devices documentation to confirm pinout and electrical characteristics. Ensure the component matches the required reset threshold and output configuration for your design. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit parts. Confirm RoHS compliance status if required by your manufacturing standards.

Supervisors Selection Notes

Select this component when a fixed 2.63V threshold is required alongside watchdog and manual reset features. Consider the SOT-23-5 package size constraints and the need for multiple output driver types. Evaluate the 10µA supply current against system power budgets. Verify that the operating temperature range meets environmental requirements.

Supervisors Part Context

This part belongs to the MAX6316–MAX6322 family of μP supervisory circuits. These devices provide combinations of reset outputs, watchdog timers, and manual resets. They are designed for digital systems requiring reliable power monitoring and processor activity tracking within compact surface-mount packages.

Supervisors Replacement Considerations

Check the MAX6316–MAX6322 family datasheet for compatible variants with different thresholds or output configurations. Verify pin compatibility before substituting other SOT-23-5 supervisor ICs.
