The illustration in Figure 3.5 shows the principal way of using the ZIOL2xxx integrated circuit in master and

device mode. Figure 3.5 does not include all required electronic components of the application circuit which are

mentioned in chapter 4 (Figure 4.1 and Figure 4.2).

3.2.2.3. Configuration

The COM and AUX drivers are built identically. Their features can be configured in a wide range. The behavior of

the output stages can be set to push, pull or push/pull. Current limitation and the overload timing can be set

individually. In order to improve the EMC system behavior the slew rate of the output signal is controlled and can

be set according to the needs of the application. The following table gives an overview of the possible

configurations for the COM and AUX driver in master and device mode, respectively.
