... The control data are transmitted via the SDI input, the timing of the serial interface is shown in Figure 4.. The device is selected with low NCS signal and the input data are transferred into the 8 bit shift register at every falling CLK edge. The rising edge of the NCS latches the new data from the shift register to the drivers. ...

... The output current is determined by the output characteristics and the output voltage depends on the load resistance. In this mode high power is dissipated in the output transistor and its temperature increases rapidly. When the power transistor temperature exceeds the thermal shutdown threshold, the overload latch is set and the corresponding output switched off ...
