8.4.2 Active Mode

The TPSF12C1 is in active mode when VVDD is above its UVLO threshold, EN is high, and there is no overtemperature fault. The simplest way to enable operation is to connect EN to VDD, which allows startup when the applied supply voltage exceeds the UVLO threshold voltage. In this mode, the device amplifies signals on COMP2 and outputs the amplified signal on the INJ pin.
