Between -40°C and 150°C an
approximately linear characteristic
line can be assumed for the short
circuit shutdown threshold.
Between 17V
U
UBatt
21V, the
short circuit shutdown threshold is
switched.
A power stage that is switched off
in case of SCB can be switched on
again by an off/on cycle at the cor-
responding input pin resp. by the
change of the state of the corre-
sponding SPI bit SCONx (see
page 16), by the μsec-Bus, by a
DEL_DIA instruction or can be
released again by reset. If the fault
register is cleared before this
release (by a DEL_DIA instruc-
tion), a new fault entry of SCB is
immediately carried out, even if
SCB condition is no longer
present.
