There are 6 independent control inputs to control the 6 MOSFETs individually. However, the control inputs for the
Highs Side MOSFETs IHx are inverted. Hence, the control inputs for High Side IHx and Low Side MOSFETs ILx
of the same half bridge can be tight together to control one half bridge by one control signal. To avoid shoot through
currents within the half bridges, a dead time is provided by the TLE7184F.
For more details about the dead time please see
5.2
The 3 low side and 3 high side powerful push-pull output stages of the TLE7184F are all floating blocks.
All 6 output stages have the same output power and thanks to the used bootstrap principle they can be switched
all up to high frequencies.
Each output stage has its own short circuit detection block. For more details about short circuit detection see
