5.4.4 Thermal Shutdown
Each output transistor includes an independent thermal shutdown circuit. When the
temperature of the output transistor exceeds a threshold value (see table below,
Item 5.4.4.1), the output transistor will be turned off and a fault bit will be set for the failed
channel. The transistor will remain off until the local transistor temperature has
decreased by the thermal hysteresis value (see table below,
Item 5.4.4.2), the output
transistor will then turn on again.
Thermal shutdown faults are channel specific.
Note: A thermal fault is latched until read via the MISO return word.
