Working Principles

The TPS3702AX33DDCT operates by comparing the input voltage (VIN) with a user-adjustable threshold voltage (SET). When the input voltage exceeds the threshold, the output (OUT) is pulled low. Conversely, when the input voltage falls below the threshold, the output is released and pulled high.

The enable pin (EN) allows the device to enter a low-power mode, reducing quiescent current consumption when voltage monitoring is not required.
