8.4 Device Functional Modes

The UCC2753x devices operate in normal mode and UVLO mode (see VDD Undervoltage Lockout 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 UCC27531 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 device uses a split output (OUTH, and OUTL) to allow for separate sourcing and sinking pins, which can help reduce ground de-bouncing.

The UCC27533 features a dual input. One inverting (IN+), and one non-inverting (IN–). This device does not contain an enable feature, and has a single output.

The UCC27536 is similar to the UCC27531, but uses an inverting input, and a single output.

The UCC27537 is also similar to the UCC27531, but uses a single output.

The UCC27538 is again similar to the UCC27531, but features dual inputs IN1 and IN2, rather than an enable and disable feature.

The UCC27531D features a single input and a single output. The device is always enabled.

See Table 2, Table 4, and Table 5 for lists of the output states of the different devices and their inputs:
