Driver section
The high-side and low-side drivers allow for the use of different types of power MOSFETs
(also multiple MOSFETs to reduce the R
low-side driver is supplied by V
A predictive dead time control avoids MOSFETs cross-conduction maintaining very short
dead time duration (see
The control monitors the phase node in order to sense the low-side body diode recirculation.
If the phase node voltage is less than a certain threshold (–350 mV typ.) during the dead
time, it will be reduced in the next PWM cycle. The predictive dead time control does not
work when the high-side body diode is conducting because the phase node does not go
