3.7 Power outputs
3.0A/45V
In case of open input (parallel con-
trol) or missing power supply the
OUT15...OUT16 power stage is switched off. Paral-
lel connection of power stages is
possible.

Above this limit short circuit to
UBatt is detected. For the duration
of the shutoff delay time tVoff (see
3.6.4) the output current is limited
to approximately this value. If the
short circuit condition is still
present after tVoff, the outputs
OUT15/16 are switched off if the
static current limitation is not
enabled. An error is stored after
tDiag (see 3.11.4).
Above this limit short circuit to
UBatt is detected. The output cur-
rent is limited to approximately this
value if the static current limitation
is configured. An error is stored
after tDiag (see 3.11.4). If the oper-
ation leads to an overtemperature
condition, a second protection
level (about 170°C) will change the
output into a low duty cycle PWM
(selective thermal shutdown with
restart) to prevent critical chip tem-
peratures.
Between -40°C and 150°C an
approximately linear characteristic
line can be assumed.
