Working Principles

The MAX6757UTLD3+T operates by comparing the input voltage (TH) with the internally set threshold voltage. When the input voltage falls below the threshold, the output (OUT) is pulled low, indicating a voltage fault or triggering an action in the connected system. The threshold voltage can be adjusted using the ADJ pin, allowing users to set the desired voltage level for monitoring.
