7.4 Device Functional Modes

The UCC27614 devices operate in normal mode and UVLO mode (see Section 7.3.1 section for information on UVLO operation). In normal mode, the output state is dependent on the states of the device, and the input pins.

The UCC27614D features a single, non-inverting input, but also contains enable and disable functionality through the EN pin. Setting the EN pin to logic HIGH will enable 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.

The UCC27614DSG features dual input; for example, IN+ and IN-. One inverting (IN-), and one non-inverting (IN+). This device does not contain a dedicated enable (EN) pin as in UCC27614D.
