Product Overview: MAX6866UK26D3L+T by Maxim Integrated

The MAX6866UK26D3L+T is a robust microprocessor (μP) supervisory circuit designed by Maxim Integrated to monitor power supplies in digital systems. It provides excellent circuit reliability and low cost by using a precision voltage reference and comparator to monitor the system voltage. This device is particularly well-suited for portable and battery-powered applications due to its low power consumption and small footprint.

Key Features

• Voltage Monitoring: The MAX6866UK26D3L+T is designed to monitor a +2.63V power supply, ensuring that the system operates within the specified voltage range.
• Reset Output: It features an active-low reset output, which remains asserted for a minimum of 140ms after VCC has risen above the reset threshold, providing ample time for the system to stabilize before the processor boots.
• Low Power Consumption: With a typical supply current of only 1.6μA, this device is optimized for energy-efficient operations, making it ideal for portable devices where battery life is critical.
• Immune to Short VCC Transients: Fast transient pulses on the VCC line are filtered, avoiding unnecessary resets and ensuring stable operation even in noisy environments.
• Compact SOT23 Package: The device comes in a tiny 5-pin SOT23 package, which is perfect for space-constrained applications.
