MAX6326UR31-T

Supervisors Overview

The MAX6326UR31+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors a single power supply input with a fixed threshold voltage of 3.1V. The device features an active-low, push-pull reset output and provides a minimum reset timeout delay of 100ms. It operates within a supply voltage range up to 5.5V and maintains functionality down to 1V. The component is designed for ultra-low-power applications with a maximum supply current of 1µA. It is housed in a compact SOT-23-3 surface-mount package and supports an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Ultra-low supply current consumption suitable for battery-powered systems
• Fixed factory-trimmed reset threshold for precise voltage monitoring
• Active-low push-pull reset output for direct logic interface
• Compact SOT-23-3 packaging for space-constrained designs

Supervisors Applications

• Portable and battery-powered equipment
• Microprocessor and microcontroller power supervision
• Intelligent instruments and controllers
• Computer power monitoring systems

Supervisors Procurement Notes

Verify the exact suffix designation (+T vs +TR) against the manufacturer's official datasheet to confirm tape-and-reel specifications. Confirm RoHS compliance status through the latest environmental certification documents provided by Analog Devices. Ensure the sourcing channel provides valid traceability for this discontinued or limited-supply component variant.

Supervisors Selection Notes

Select this component when a fixed 3.1V threshold is required for system supervision. The push-pull output eliminates the need for external pull-up resistors compared to open-drain variants. Consider the 1µA quiescent current for strict power budget constraints in portable devices requiring reliable power-fail detection without manual reset inputs.

Supervisors Part Context

This part belongs to the MAX6326/MAX6327/MAX6328 family of 3-pin, ultra-low-power SC70/SOT reset circuits. These devices monitor power supplies in microprocessor and digital systems to ensure reliability. The MAX6326 series specifically offers push-pull outputs, distinguishing it from the open-drain MAX6328 series within the same low-power footprint.
