Input circuit (ESD protection), IN1 or IN2

GND

ESD-ZD

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).

Status output, ST1 or ST2

GND

ESD-

+5V

R ST(ON)

ESD-Zener diode: 6.1 V typ., max 5.0 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 resul

t 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!
