Working Principles

The MAX6385XS17D4-T operates by comparing the input voltage with the threshold voltage set by the user. When the input voltage exceeds the threshold, the digital output (OUT pin) is pulled low. Conversely, when the input voltage falls below the threshold, the output remains high impedance.

The adjustable threshold voltage allows the device to be used in various applications where different voltage levels need to be monitored. The low quiescent current ensures minimal power consumption, making it suitable for battery-powered systems.
