Functional Features

• Monitors supply voltage and asserts reset when it falls below the selected threshold.
• Provides manual reset capability through the MR pin.
• Low quiescent current makes it suitable for battery-powered applications.
• Power-on reset delay ensures stable operation during power-up.

Advantages and Disadvantages

Advantages: - Wide supply voltage range allows compatibility with various systems. - Multiple threshold voltage options provide flexibility for different voltage monitoring requirements. - Low quiescent current minimizes power consumption. - Small package size enables space-constrained designs.

Disadvantages: - Limited to voltage monitoring applications. - Manual reset input may require additional external components for proper functionality.

Working Principles

The MAX6861UK17+T operates by continuously monitoring the supply voltage. When the voltage falls below the selected threshold, the active-low reset output (RST) is asserted, indicating a power failure or an out-of-tolerance condition. The manual reset input (MR) allows the user to manually assert a reset signal when required.
