GND
Ground:
Reference potential
Important: for the capability of driving the full current at the outputs all
pins of GND must be externally connected.

OUT8
Highside driver output 8
The 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. The highside driver is a power
DMOS transistor with an internal parasitic reverse diode from the
output to VS (bulk-drain-diode). The output is over-current and open
load protected.
Important: for the capability of driving the full current at the outputs both
pins of OUT8 must be externally connected.

OUT3
Half-bridge-output 1,2,3
The output is built by a highside and a lowside switch, which are
internally connected. The output stage of both switches is a power
DMOS transistor. Each driver has an internal parasitic reverse diode
(bulk-drain-diode: highside driver from output to VS, lowside driver from
GND to output). This output is over-current and open load protected.
