MAX6326XR31

Supervisors Overview

The MAX6326XR31+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.2V to 5.5V and features a fixed reset threshold voltage of 3.08V. The device provides an active-low, push-pull/totem-pole output with a minimum reset timeout period of 185ms. It is housed in a compact SC-70 (SOT-323) surface-mount package and supports an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Monitors power-supply voltages and asserts a reset signal when the supply falls below the factory-set threshold.
• Provides a guaranteed valid reset for supply voltages down to 1V.
• Features a push-pull active-low reset output stage.

Supervisors Applications

• Microprocessor (µP) supervisory circuits
• Digital system power monitoring
• Portable equipment power management

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to discontinued status. Confirm RoHS compliance and lead-free specifications against current manufacturing records. Check for potential obsolescence notices or product change notifications affecting long-term availability. Ensure packaging details match design requirements.

Supervisors Selection Notes

Select this component for applications requiring a fixed 3.08V threshold with an active-low push-pull output. Consider the 185ms minimum timeout and SC-70 package constraints. Verify compatibility with system voltage ranges between 1.2V and 5.5V. Evaluate thermal performance within the specified -40°C to +85°C operating range.

Supervisors Part Context

Part of the MAX6326 family of ultra-low-power µP reset circuits. Designed for portable applications where low current consumption and small package size are critical. Shares functional similarities with other MAX63xx series devices but differs in specific threshold voltages and output configurations.

Supervisors Replacement Considerations

MAX6326XR24+T offers similar functionality with a different threshold voltage (2.4V). MAX6326UR23+T provides comparable features in a SOT-23-3 package. Verify pinout compatibility and electrical parameters before substitution.
