MAX6324AUT31+T

Supervisors Overview

The MAX6324AUT31+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors power supplies in digital systems with a fixed reset threshold of 3.08V and ±2.5% accuracy. The device features an open-drain RESET output that remains asserted low when the supply voltage falls below the threshold or when the manual reset input is activated. Valid RESET output is guaranteed down to VCC = +1.2V. It operates within a temperature range of -40°C to +125°C and is housed in a SOT-23-6 surface-mount package.

Supervisors Feature Summary

• Monitors power supply voltage levels with laser-trimmed accuracy for reliable system supervision
• Provides open-drain RESET output assertion when supply voltage drops below the specified threshold
• Includes manual reset input capability for external control of the reset state
• Integrates windowed watchdog timer functionality to detect processor activity anomalies

Supervisors Applications

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

Supervisors Procurement Notes

Verify the exact suffix (+T) indicates tape-and-reel packaging configuration. Confirm the manufacturer designation as Analog Devices Inc. or Maxim Integrated, as both entities are associated with this product line. Ensure the part number matches the specific 3.08V threshold variant required for your design. Check for RoHS compliance status indicated by the '+' symbol in the part number. Validate the SOT-23-6 package type against your PCB footprint requirements.

Supervisors Selection Notes

Select this component when a fixed 3.08V reset threshold is required for power supply monitoring. Choose the open-drain output version if interfacing with multiple voltage domains or requiring wired-OR configurations. Consider the wide operating temperature range for industrial applications. Verify compatibility with the system's minimum operating voltage, as valid reset is guaranteed down to 1.2V. Ensure the manual reset input logic level aligns with the system's control signals.

Supervisors Part Context

The MAX6324 series belongs to Maxim Integrated's family of µP supervisory circuits designed for monitoring power supplies and processor activity. These devices typically include windowed watchdog timers and manual reset inputs. The MAX6324 specifically offers an open-drain output, distinguishing it from the push-pull MAX6323 variant. The series provides multiple laser-trimmed threshold options to accommodate various supply voltage requirements in digital systems.

Supervisors Replacement Considerations

Public confirmed substitute part numbers: MAX6324AUT31+ (non-tape reel), MAX6324CUT31+T (alternative manufacturer source). Verify pinout compatibility and electrical specifications before substitution.
