The MAX6806US26 from Maxim Integrated is a compact, highly reliable microprocessor (µP) supervisory circuit designed to maintain system integrity during power failures or unexpected brown-out conditions. This device is engineered to monitor the supply voltage of digital systems and provide a reset signal to the host microprocessor during power-up, power-down, and brown-out conditions, ensuring that the µP starts up in a known state every time.

Key Features

• Precision Voltage Monitoring: The MAX6806US26 offers precise monitoring of the 2.63V voltage threshold, suitable for systems operating at 2.7V and above.
• Low Power Consumption: With its low quiescent current of only 1.5µA, this device is ideal for power-sensitive applications, contributing to the overall energy efficiency of the system it is protecting.
• Manual Reset Input: A manual reset input is provided, allowing for a reset to be triggered externally when necessary.
• Reset Timeout: The reset output remains asserted for a minimum timeout period after VCC has risen above the reset threshold, ensuring the system has adequate time to stabilize.
• High Reset Output Sink Current: The device supports a high sink current on the reset output, enabling direct connection to the reset line without additional buffering.
• Compact SOT Package: The MAX6806US26 comes in a space-saving SOT-143 package, making it suitable for use in applications where board space is at a premium.

Applications

The MAX6806US26 is versatile and can be used in a variety of applications, including:

• Portable/Battery-Powered Equipment
