7.2.5 Pre-Driver
The pre-driver block provides three high-side pre-drivers and three low-side pre-drivers to drive external N-
channel MOSFETs. The turn on side of the high-side pre-drivers supply the large N-channel transistor current to
quickly charge and PMOS support output voltage up to PDCPV. The turn off side supplies the large N-channel
transistor current to quickly discharge, while the low-side pre-drivers supply the large N-channel transistor current
for charge and discharge. The output voltage of the low-side pre-driver is controlled by VB and it has VGS
protection to make less than 18 V. The pre-driver has a stop condition in some fault conditions ($16 Error
Detection).
