Each output transistor includes an independent thermal shutdown circuit. When the
temperature of the output transistor exceeds a threshold value (see table below,

channel. The transistor will remain off until the local transistor temperature has
decreased by the thermal hysteresis value (see table below,
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.
