4.2.2
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).
The power-stages are subdivided into two groups for over-temperature shut-down:
• Group1: OUT 1, OUT 2 and OUT 3
• Group2: OUT 4 to 11
If one or more temperature sensors within a group reaches the shutdown threshold, all
outputs within the group are switched off, while the other outputs continue normal
operation.
