PROTECTION CIRCUITS
DUAL HIGH SIDE SWITCH
The simplest way to protect the device against a
continuous reverse battery voltage (-26V) is to
insert a a small resistor between pin 2 (GND) and
ground. The suggested resistance value is about
150 . In any case the maximum voltage drop on
this resistor should not overcome 0.5V.
TRUTH TABLE (for Dual high-side switch only)
NOTE: The low-side switches have the fault feedback which can be detected by monitoring the voltage at the input pins.

INPUT 2
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
