TLE7184F-3V
Description of Modes, Protection and Diagnostic Functions
9.2.2 Analog Temperature Monitoring
The TEMP output of the TLE7184F-3V provides an analog voltage signal proportional to the chip temperature.
This function is not available in Deadlock Mode.
9.2.3 VS Under Voltage Lockout (VS_UVLO)
The TLE7184F-3V has an integrated VS Under Voltage Lockout to assure that the behavior of the complete IC is
predictable in all supply voltage ranges.
If the supply voltage at VS reaches the Under Voltage shut down level V_VSLO for a minimum specified filter time
the IC goes into Go-to-Sleep Mode and finally into Sleep Mode.
9.2.4 VDD Under Voltage Diagnosis (VDD_UVD)
The TLE7184F-3V 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 V_UVVDD for a minimum specified filter time, an error
is set and the IC goes into Error Mode.

9.2.5 VDD Under Voltage Shut Down (VDD_UVSD)
The TLE7184F-3V 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 V_VDDsleep and the wake-up time is expired,
VREG and VDD will be switched off and the IC will go to the Deadlock Mode.
