The MAX6326UR28 from Maxim Integrated is a highly precise, low-power microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used with 2.8V-powered circuits.

Key Features:

• Precision Voltage Monitoring: The MAX6326UR28 offers a factory-preset reset threshold voltage of 2.8V, making it ideal for monitoring 2.8V power supplies and ensuring that the µP resets reliably under all conditions.
• Low Power Consumption: With its low supply current of only 1µA (typical), this supervisory circuit is optimized for battery-powered equipment, contributing to extended battery life.
• Manual Reset Input: This feature allows a pushbutton or external logic signal to initiate a system reset, providing additional system control and flexibility.
• Reset Output Stage: The open-drain reset output ensures compatibility with multiple µP and logic families, and it remains asserted for a minimum of 140ms (typical) after VCC has risen above the reset threshold, allowing the system to stabilize.
• Temperature Range: The device operates over a wide temperature range of -40°C to +85°C, suitable for various industrial applications.

Applications:

The MAX6326UR28 is versatile and can be used in an array of applications, including:

• Portable/Battery-Powered Equipment
• Computers and Controllers
• Embedded Systems
• Data Storage Equipment
• Medical Devices

Package and Availability:

The device is available in a compact SOT23-3 package, providing a space-saving solution for PCB design. The MAX6326UR28's small footprint and precision features make it an excellent choice for designers looking to enhance system reliability with minimal power consumption and space requirements.
