OUT1
ESD zener diodes are not to be used as voltage clamp
at DC conditions. Operation in this mode may result in
a drift of the zener voltage (increase of up to 1 V).

With additional external pull up resistor
An external short of output to Vbb, in the off state, causes an internal current from output to ground. If RGND
is used, an offset voltage at the GND and ST pins will occur and the VST low signal may be errorious.
Low resistance to Vbb may be detected in the ON-state by the no-load-detection
