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

OUT11
Highside driver output 11.
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 OUT11 must be externally connected.

* Note: Value of capacitor has to be choosen carefully to limit the VS
voltage below absolute maximum ratings in case of an unexpected
freewheeling condition of inductive loads (e.g. TSD, POR)
*
** Note: Resistors between C and L9950 are recommended to limit currents
for negative voltage transients at VBAT (e.g. ISO type 1 pulse)
+ Note: Using a ferrite instead of 10ohm will additionally improve EMC behavior
