There are four input pins available at TLE8108EM, which can be configured to be used for control of the output
stages. The SPI INn parameter selects the input pin to be used.
Figure 5
The current sink to ground ensures that the channels switch off in case of an open input pin. The zener diode
protects the input circuit against ESD pulses. After power-on reset or after an external reset the device enters the
OFF mode for all channels. During an external reset or a power-on reset, the output stages are set to Clear mode.
