This resistor can be shared amongst several different
HSD. Please note that the value of this resistor should be
calculated with formula (1) where I
sum of the maximum on-state currents of the different
devices.
Please note that if the microprocessor ground is not
common with the device ground then the R
produce a shift (I
and the status output values. This shift will vary
depending on how many devices are ON in the case of

If the calculated power dissipation leads to a large
resistor or several devices have to share the same
resistor then the ST suggests to utilize Solution 2 (see
below).

D
This small signal diode can be safely shared amongst
several different HSD. Also in this case, the presence of
the ground network will produce a shift (
input threshold and the status output values if the
microprocessor ground is not common with the device
ground. This shift will not vary if more than one HSD
shares the same diode/resistor network.
Series resistor in INPUT and STATUS lines are also
required to prevent that, during battery voltage transient,
the current exceeds the Absolute Maximum Rating.
Safest configuration for unused INPUT and STATUS pin
is to leave them unconnected.
