6.4 Device Functional Modes

The UCC27614-Q1 devices operate in normal mode and UVLO mode (see Section 6.3.1 for information on UVLO operation). In normal mode, the output state is dependent on the states of the device, and the input pins.

The UCC27614-Q1 DSG features dual input, one inverting (IN-), and one non-inverting (IN+). This device does not contain a dedicated enable (EN) pin as in the UCC27614-Q1 D and DGN.

The UCC27614-Q1 D and DGN feature a single, non-inverting input, but also contain enable and disable functionality through the EN pin. Setting the EN pin to logic HIGH enables the non-inverting input to output on the IN pin. The two OUT pins are internally shorted and shall be shorted on the application board as well.
