OUT6,

OUT7

Highside driver output 6,7:

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.
