Working Principles

The TPS3700DSET operates by comparing the input voltage (VIN) with a user-adjustable threshold voltage (TH). When the input voltage falls below the threshold, the output (OUT) is pulled low. Conversely, when the input voltage rises above the threshold, the output is released and pulled high. This behavior allows the IC to monitor and supervise the voltage level in a system.
