Two external smart power drivers can be driven by the SPOC - BTS6480SF via the external driver control block.
For each external driver there are two control outputs available: one output for controlling the input (EDOx) and
one output for diagnosis enable input (EDDx). The current sense output of the external smart power drivers can
be connected to the IS pin. For details please refer to
The external driver outputs can be used only with applied
pulled down. The external drivers can be activated via SPI-bits OUT.OUT4 and OUT.OUT5 or via the input pin
IN3 in assigned drive mode. They will be served as well by the integrated automatic PWM-generation. Therefore,
the according PWM-frequency and duty cycle needs to be programmed.
For performing diagnosis on the external drivers they 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. The DSEL will be set depending on the multiplexer setting
DCR.MUX.
