Temperature sensors are integrated in the power stages. The temperature monitoring circuit compares the
measured temperature to the warning and shutdown thresholds. If one or more temperature sensors reach the
warning temperature, the temperature warning bit TW is set to HIGH. This bit is not latched (i.e. if the temperature
falls below the warning threshold (with hysteresis), the TW bit is reset to LOW again).
If one or more temperature sensors reach the shut-down temperature, the outputs are shut down as described in
the next paragraph and the temperature shut-down bit TSD is set to HIGH. The shutdown is latched (i.e. the output
stages remain off and the TSD bit set high until a SRR command is sent or a power-on reset is performed).
If one or more temperature sensors reaches the shutdown threshold, all outputs are switched off.

Under Voltage
If the supply voltage
the power supply fail bit PSF is set. The error is not latched, i.e. if

Over Voltage
If the supply voltage
the power supply fail bit (bit 7 of the SPI diagnosis word) is set. The error is not latched, i.e. if
