MAX6322HPUK29C-T

Supervisors Overview

The MAX6322HPUK29C-T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1V to 5.5V and features a fixed reset threshold voltage of 2.9V. The device provides a push-pull active-low reset output with a selectable timeout delay. It includes integrated watchdog timer functionality and a manual reset input for system control. The component is housed in a compact SOT-23-5 surface-mount package, designed for reliable operation across an extended industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer and manual reset input for comprehensive system supervision
• Provides a factory-trimmed fixed reset threshold voltage for precise monitoring
• Features a push-pull active-low reset output compatible with various logic families

Supervisors Applications

• Microprocessor power supply monitoring in digital systems
• Watchdog timer implementation for processor activity tracking
• Manual reset circuit integration for user-initiated system recovery

Supervisors Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration when sourcing. Confirm that the 'HPUK' designation aligns with the required SOT-23-5 package variant and lead-free compliance status. Ensure the fixed 2.9V threshold matches the target application's voltage requirements before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a fixed 2.9V threshold is required alongside integrated watchdog capabilities. The push-pull output simplifies interface design compared to open-drain alternatives. Consider the SOT-23-5 footprint for space-constrained portable applications requiring low quiescent current and robust supervisory functions.

Supervisors Part Context

This part belongs to the MAX6316–MAX6322 family of 5-pin microprocessor supervisory circuits. The family offers various combinations of reset outputs, watchdog timers, and manual reset inputs. These devices are designed to monitor power supplies and processor activity, providing reliable system reset signals in complex digital environments.

Supervisors Replacement Considerations

Cross-reference other MAX6322 variants with different threshold voltages or timeout delays if the 2.9V setting does not match the new design requirements. Verify pinout compatibility when substituting with other members of the MAX6316–MAX6322 series.
