MAX6323EUT29-T

Supervisors Overview

The MAX6323EUT29-T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors power supplies and microprocessor activity in digital systems, featuring a windowed watchdog timer and manual reset capability. The device operates within a supply voltage range of 1.2V to 5.5V and utilizes a SOT-23-6 surface-mount package. Key electrical parameters include a fixed reset threshold voltage of 2.93V with ±2.5% accuracy, a reset delay time of 180ms, and a quiescent current of 27µA. It supports an operating temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Integrates a windowed watchdog timer to detect abnormal system activity outside expected operational windows.
• Provides a push-pull active-low RESET output that asserts when the supply voltage falls below the threshold or upon manual reset assertion.
• Ensures valid RESET output down to a minimum supply voltage of 1.2V for reliable low-voltage monitoring.

Supervisors Applications

• Monitoring power supplies in embedded digital systems
• Supervising microprocessor activity via watchdog timer functionality
• Providing manual reset control for system recovery

Supervisors Procurement Notes

Verify component authenticity through authorized distributors due to potential availability constraints. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Ensure the ordering suffix matches the required package and temperature grade specifications exactly as defined in the official datasheet to avoid functional mismatches.

Supervisors Selection Notes

Select this component when a fixed 2.93V threshold is required for system supervision. Consider the SOT-23-6 package for space-constrained designs. Evaluate the 27µA quiescent current against system power budgets. Verify compatibility with the target microprocessor's reset timing requirements given the 180ms delay characteristic.

Supervisors Part Context

The MAX6323 series belongs to Maxim Integrated's uP Supervisory Circuits family, designed for monitoring power supplies and processor activity. This specific variant features a windowed watchdog and manual reset, distinguishing it from simpler supervisor variants. It complements other MAX6323 models offering different thresholds or open-drain outputs.

Supervisors Replacement Considerations

MAX6323EUT29+T serves as a direct lead-free replacement variant within the same series. Cross-reference with MAX6323HUT29+T if higher accuracy is needed, though threshold values may differ. Verify pinout and electrical characteristics against original design specifications before substitution.
