If the supply voltage at VS reaches the Under Voltage shut down level
the IC goes into Go-to-Sleep Mode and finally into Sleep Mode.
9.2.5
The TLE7184F has an integrated VDD Under Voltage Diagnosis, to assure that the behavior of the bridge driver
output stages is predictable in all supply voltage ranges.
If the voltage at VDD reaches the Under Voltage diagnosis level
is set the IC goes into Error Mode.
Figure 10
9.2.6
The TLE7184F has an integrated VDD Under Voltage Shut Down, to avoid operation with VDD shorted to GND.
If the supply voltage at VDD reaches the Under Voltage shut down level
VREG and VDD will be switched off and the IC will go to the Deadlock Mode.
9.2.7
The TLE7184F has an integrated VREG Under Voltage Diagnosis, to assure that the behavior of the bridge driver
output stages is predictable in all supply voltage ranges.
If the voltage at VREG reaches the Under Voltage diagnosis level
is set the IC goes into Error Mode.
