The SD input pin controls the outputs by turning GH and GL off when the SD pin is held low, regardless of the IN input pin state. When SD pin is held high, the IN pin controls the state of the GL and GH outputs allowing the device to be used in single PWM input applications. When IN pin is low, GL output will turn on and GH output will turn off, and when IN pin is high, GL output will turn off and GH output will turn on.

The device has built-in fixed dead time with a typical value of 475 ns. A small filter at each of the inputs of the driver further improves system robustness in noise-prone applications. Both IN and SD have internal pulldown resistors with typical value of 200 kΩ. Thus, when the inputs are floating, the outputs are held low.
