Highside-driver-output 4 and 5
Each output is built by a highside switch and is intended for resistive
loads, hence the internal reverse diode from GND to the output is
missing. For ESD reason a diode to GND is present but the energy
which can be dissipated is limited. Each highside driver is a power
DMOS transistor with an internal parasitic reverse diode from each
output to VS (bulk-drain-diode). Each output is over-current and open
load protected.
