Working Principles

The MAX705ESA is a voltage supervisor IC that monitors the power supply voltage of a system. It compares the supply voltage with a preset threshold voltage and generates a reset signal when the supply voltage drops below the threshold. The reset signal remains active until the supply voltage rises above the threshold again.

The device operates over a wide supply voltage range and offers multiple threshold voltage options to suit different applications. It consumes low power, making it suitable for battery-powered systems. Additionally, it provides a manual reset input for added control flexibility.
