Time Power
Switches
Time from occurrence of one of
the errors ’short to ground’, ’open
load’ or ’short to battery’ until the
fault is entered into the corre-
sponding diagnostic register.
Time from occurrence of OT until
the information is entered into the
corresponding diagnostic register.

Pulsed power stage.
Neighboring stages, reset, input
signals of the power stages, VDD-
monitoring, SPI interface (incl. reg-
isters) and μsec-bus must not be
disturbed. Diagnostics of fault con-
ditions at neighboring stages is still
possible. Control bits in the SPI
registers (serial control of power
stages are not disturbed).
Open load failure at neighboring
stages may be detected as short
to ground
