MAX6323HUT29-T

Supervisors Overview

The MAX6323HUT29-T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors power supplies and processor activity in digital systems, featuring a windowed watchdog timer and manual reset input. The device provides a push-pull RESET output asserted low when VCC falls below the fixed threshold of 2.93V or upon manual assertion. Valid RESET output is guaranteed down to VCC = +1.2V. It operates within a supply voltage range up to 5.5V and supports an operating temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Integrates a windowed watchdog timer to detect out-of-specification system activity
• Provides a manual reset input for external control of the reset state
• Features a push-pull output driver ensuring robust signal integrity
• Maintains valid reset functionality at low supply voltages

Supervisors Applications

• Microprocessor power supply monitoring
• Digital system watchdog supervision
• Embedded controller reset management

Supervisors Procurement Notes

Verify the exact suffix against official manufacturer documentation to confirm tape-and-reel packaging and specific threshold accuracy. Confirm RoHS compliance status and lead-free designation with the supplier. Ensure the part number matches the specific laser-trimmed threshold voltage required for the design. Check for any obsolescence notices or limited availability warnings directly from Analog Devices.

Supervisors Selection Notes

Select this component when a fixed 2.93V threshold is required for single-channel power monitoring. The push-pull output is suitable for driving loads without external pull-ups. Consider the SOT-23 package size for space-constrained designs. Verify that the 180ms reset delay time aligns with the target system's startup requirements.

Supervisors Part Context

This part belongs to the MAX6323/MAX6324 family of µP supervisory circuits. The 'H' indicates a specific threshold voltage bin, while 'T' denotes tape-and-reel packaging. The MAX6323 variant specifically offers a push-pull output, distinguishing it from the open-drain MAX6324. These devices are designed for reliable operation in harsh industrial and commercial environments.

Supervisors Replacement Considerations

MAX6323HUT29+ is the non-tape reel equivalent. MAX6323FUT29+T offers similar functionality with potentially different threshold tolerances. Cross-reference datasheets for pinout compatibility and electrical parameter alignment before substitution.
