TLE7186F

Description of Modes, Protection and Diagnostic Functions

9.2.4

VS Under Voltage Lockout (VS_UVLO)

The TLE7186F 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

VSLO for a minimum specified filter time

the IC goes into Go-to-Sleep Mode and finally into Sleep Mode.

9.2.5

VDD Under Voltage Diagnosis (VDD_UVD)

The TLE7186F 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

UVVDD for a minimum specified filter time, an error

is set and the IC goes into Error Mode.

Timing of VDD Under Voltage Diagnosis

9.2.6

VDD Under Voltage Shut Down (VDD_UVSD)

The TLE7186F 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

VDDsleep and the wake-up time is expired,

VREG and VDD will be switched off and the IC will go to Deadlock Mode.

9.2.7

VREG Under Voltage Diagnosis (VREG_UVD)

The TLE7186F 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.
