WAKEUP[3:0]
Configures the 8-bit code value corresponding to temperature threshold
Temp
Wakeup
. Upon power-up the system will enter an external overtempera-
ture fault disabling the power train, unless the external temperature measured
at the external NTC is below Temp
Wakeup
. If the temperature drops below this
threshold, the device will clear all overtemperature faults. The setting is an off-
set to Temp
eOTP
(see “Configuration 59 (Config59) – Address 91” on page 48
for configuring Temp
eOTP
).
The equation above is setting 8-bit code, CODE
TEMPWakeup
, corresponding to
temperature Temp
Wakeup
, which is in degrees Celsius. The wakeup tempera-
ture code is configured as an offset from the eOTP temperature code and the
shutdown temperature code is configured as an offset from the wakeup tem-
perature code; Temp
eOTP
< Temp
Wakeup
< Temp
Shutdown
.
