V Z1 = 6,1V typ., V Z2 = 47V typ., R GND = 150
R IS = 1k , R I = 3,5k typ.
In case of reverse battery the load current has to
be limited by the load. Protection functions are
not active.
Open load detection, OUT1 or 2
Off-state diagnostic condition:
Open load, if V OUT > 3 V typ.; IN = low
GND disconnect

Vbb disconnect with energized inductive
load
For inductive load currents up to the limits defined
by Z L each switch is protected against loss of V bb .
(max. ratings and diagram on page 12)
Consider at your PCB layout that in the case of Vbb
disconnection with energized inductive load all the
load current flows through the GND connection.
