Functional Description
2.6.2 Adjustable self adapting Dead Time
The dead time between the turn OFF and turn ON of the half – bridge drivers is adjustable (C16 see
Figure 3) and detected via a second threshold (– 50 mV) of the LSCS voltage. The range of the dead
time adjustment is 1.05 µs up to 2.0 µs during all operating modes. Start of the dead time
measurement is the OFF switching of the high side MOSFET. The finish of the dead time
measurement is, when V
drops for longer than typical 280ns (internal fixed propagation delay)
LSCS
below -50mV. This time will be stored (stored dead time) and the low side gate driver switches ON.
The high side gate driver turns ON again after OFF switching of the low side switch and the stored
dead time.
