For diagnosis purpose, the SPOC - BTS6460SF provides a current sense signal at pin IS and the diagnosis word
via SPI. There is a current sense multiplexer implemented that is controlled via SPI. The sense signal can also be
disabled by SPI command. A switch bypass monitor allows to detect a short circuit between the output pin and the
battery voltage.
In OFF-state a current source is able to be switched on for a selected channel with the DCR.CSOL bit. This allows
open load / short circuit detection to
by programming the bit IECR.CSL. Please refer to parameter
