Solution 2: diode (D

inductive load.
This small signal diode can be safely shared amongst several different HSDs. Also in this
case, the presence of the ground network will produce a shift (≈600mV) in the input
threshold and in the status output values if the microprocessor ground is not common to the
device ground. This shift will not vary if more than one HSD shares the same diode/resistor
network.
Series resistor in INPUT lines is also required to prevent that, during battery voltage
transient, the current exceeds the absolute maximum rating.
Safest configuration for unused INPUT pin is to leave it unconnected, while unused SENSE
pin has to be connected to ground pin.

MCU I/Os protection
If a ground protection network is used and negative transient are present on the V
the control pins will be pulled negative. ST suggests to insert a resistor (R
prevent the µC I/Os pins to latch-up.
The value of these resistors is a compromise between the leakage current of μC and the
current required by the HSD I/Os (Input levels compatibility) with the latch-up limit of μC
I/Os.
