TLE 6244X
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 bit for SPI or 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.
For OUT9, OUT10
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 t_Diag (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.
