The MAX709RESA+T from Maxim Integrated is a compact, 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 5V-powered circuits.

Key Features

• Precision Monitoring: This device offers precise monitoring of the 5V power-supply voltages with a factory-set reset threshold voltage. It ensures that the systems it monitors are operating at optimal power levels, thereby safeguarding the integrity of the processes they control.
• Reset Output: The MAX709RESA+T features an active-low reset output, which remains asserted for a minimum of 140ms after VCC has risen above the reset threshold. This reset timing ensures proper system reset, allowing the connected microprocessor and other digital systems enough time to initialize properly.
• Low Power Consumption: With its low power consumption, this device is ideal for use in portable and battery-operated applications, ensuring that the power monitoring function does not significantly drain the system's resources.
• Manual Reset Input: An additional feature of the MAX709RESA+T is the manual reset input, which allows for a manual triggering of the reset function, providing an extra layer of control for system operators.
• Compact SOT-23 Packaging: The device comes in a small 8-pin SOT-23 package, making it suitable for space-constrained applications without compromising performance.
