MAX6327UR26+

Supervisors Overview

The MAX6327UR26+T is a 3-pin, ultra-low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors a single voltage input with a threshold of 2.6 V and features an active-high, push-pull reset output. The device operates within a supply voltage range up to 5.5 V and draws a maximum operating current of 1 µA. It provides a fixed reset delay time of 185 ms and maintains accuracy within 2.5%. The component is housed in an SOT-23-3 package and functions reliably across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Ultra-low power consumption with a maximum supply current of 1 µA for portable applications
• Active-high push-pull reset output configuration
• Precision voltage monitoring with factory-trimmed thresholds
• Compact SOT-23-3 surface-mount packaging

Supervisors Applications

• Portable/battery-powered equipment
• Computers and power monitoring systems
• Intelligent instruments
• Controllers and critical microprocessor systems

Supervisors Procurement Notes

Verify the specific suffix UR26 against the official datasheet to confirm the exact threshold voltage and package type. Ensure the ordering part number matches the required output configuration and tolerance specifications. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability may vary.

Supervisors Selection Notes

Select this component when an active-high reset signal is required for low-voltage digital systems. The 1 µA quiescent current makes it suitable for battery-operated devices where power efficiency is critical. Verify that the 2.6 V threshold aligns with the monitored rail and that the SOT-23-3 footprint fits the design constraints.

Supervisors Part Context

This part belongs to the MAX6326/MAX6327/MAX6328 family of 3-pin, ultra-low-power SC70/SOT μP reset circuits. These devices monitor power supplies in microprocessor and digital systems to ensure reliability by asserting a reset signal when the supply voltage declines below a preset threshold. The family eliminates external components and adjustments for standard voltage rails.
