9.2. OVERTEMPERATURE Error
When the temperature of the power semiconductors exceeds 80 °C, an OVERTEM-
PERATUR Error is released.
When the temperature is below 75 °C again, this error can be cleared by Reset
signal
Ensure sufficient cooling if necessary.
9.3. SHORTCIRCUIT Error
When the output current of the power stage exceeds a certain level, a SHORTCIR-
CUIT Error is released. The short circuit detector is implemented in hardware and
therefore reacting fast (no software latency). In this way, the output stage is protect-
ted from damage. Under normal operating conditions this current level is out of
reach.
