PROTECTION CIRCUITS
DUALHIGH SIDE SWITCH
The simplest way to protect the device against a
continuous reverse battery voltage (-26V) is to
insert a a smallresistor betweenpin 2 (GND) and
ground. The suggested resistance value is about
150
. In any case the maximumvoltage drop on
this resistor should not overcome 0.5V.
If there is no need for the control unit to handle
external analog signals referred to the power
GND, the best approach is to connect the
reference potential of the control unit to the
device ground (see application circuit in fig. 3),
which becomes the common signal GND for the
whole control board avoiding shift of V
ih
, V
il
and
V
stat
.
