6.4 Device Functional Modes

The UCC5710x-Q1 devices operate in normal mode and UVLO mode (see Section 7.2.2.1 for information on UVLO operation). In normal mode, the output state is dependent on the states of the device and the input pins.

The UCC5710xW-Q1 features a single, noninverting input, but also contains enable and disable functionality through the EN pin. Setting the EN pin to logic HIGH enables the noninverting input to output on the IN pin.
