MAX6323BUT26

Supervisors Overview

The MAX6323BUT26+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors power supplies and microprocessor activity in digital systems using a windowed watchdog timer and manual reset functionality. The device features a push-pull output type and operates within a supply voltage range up to 5.5 V. It provides a fixed reset threshold of 2.63 V with ±2.5% accuracy. The circuit ensures valid RESET output down to VCC = +1.2 V and includes a reset delay time of 180 ms. It consumes 27 uA of operating current and functions across an industrial temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Integrates a windowed watchdog timer to detect out-of-specification system activity
• Provides manual reset input capability for external control
• Features laser-trimmed reset thresholds with high accuracy
• Delivers active low push-pull reset output

Supervisors Applications

• Microprocessor power supply monitoring
• Digital system supervision
• Watchdog timer implementation in embedded controllers

Supervisors Procurement Notes

Verify the specific suffix 'BUT' against official datasheets to confirm the exact threshold voltage, as variations exist within the MAX6323 family. Confirm RoHS compliance status and lead times directly with authorized distributors or Analog Devices, as availability may vary by region. Ensure the package type matches the design requirements before ordering.

Supervisors Selection Notes

Select this component when a windowed watchdog timer and manual reset are required alongside voltage supervision. Compare the 2.63 V threshold against system rail voltages to ensure proper triggering. Consider the SOT-23-6 package size for space-constrained designs. Verify that the 27 uA quiescent current meets low-power requirements.

Supervisors Part Context

The MAX6323 series belongs to Maxim Integrated's line of µP supervisory circuits designed for reliable system management. These devices combine voltage monitoring with activity tracking via a watchdog timer. The MAX6323 variant specifically offers a push-pull output, distinguishing it from the open-drain MAX6324. This series supports various fixed thresholds to accommodate different logic families and supply rails.

Supervisors Replacement Considerations

MAX6323BUT29+T: Different reset threshold (2.93 V). MAX6323HUT26+T: Higher accuracy (±1.5%) but potentially different electrical characteristics. MAX6324BUT26+T: Open-drain output instead of push-pull.
