ESD-
ZD
ESD-Zener diode: 6.1 V typ., max 5 mA;
RST(ON) < 0 Ω at 1.6 mA, 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).
Short circuit detection
Fault Signal at ST-Pin: VON > 2.5 V typ, no switch off by
the PROFET itself, external switch off recommended!
