TLE956x, TLE9210x: Purpose of the VS/VSINT brake feature
The VS/VSINT overvoltage brake is intended to protect the application, when a motor operates in generator mode.
The operation in generator mode can occur in several cases such as:
* The motor rotation is caused by the application of an external torque, such as the manual closure of the trunk lid or of a sliding door
* While the motor is activated by the half-bridges, then the MOSFETs are turned off without any active brake
An example of a manually closed trunk lid causing VS overvoltage conditions [can be found here].
Turn-on of the low-side MOSFETs during a VS/VSINT overvoltage brake event [to be found here].
