VZ1 = 6.1 V typ., VZ2 = 47 V typ., RGND = 150 Ω,
RST= 15 kΩ, RI= 3.5 kΩ typ.
In case of reverse battery the load current has to be
limited by the load. Temperature protection is not active
Open-load detection OUT1 or OUT2
ON-state diagnostic
Open load, if VON < RON·IL(OL); IN high
ESD-Zener diode: 6.1 V typ., max 5.0 mA; RST(ON) < 375 Ω
at 1.6 mA. The use of ESD zener diodes as voltage clamp at
DC conditions is not recommended.

VGND
Any kind of load. In case of IN = high is VOUT ≈ VIN - VIN(T+).
Due to VGND > 0, no VST = low signal available.
