Current Sense Multiplexer
There is a current sense multiplexer implemented in the SPOC - BTS6480SF that routes the sense current of the
selected channel to the diagnosis pin IS. The channel is selected via SPI register DCR.MUX. The sense current
also can be disabled by SPI register DCR.MUX. For details on timing of the current sense multiplexer, please refer
to
The current sense diagnosis enable signal for the external smart power drivers also can be selected via the SPI
register DCR.MUX. For being compliant to PROFET+ diagnostic functions, it is possible to configure pin EDD0 as
DEN and EDD1 as DSEL. Therefore, the bit IECR.PRO+ needs to be set.
