Please note that, if the microprocessor ground is not common with the device ground, then
the R
values. This shift varies depending on how many devices are ON in the case of several high-
side drivers sharing the same R
If the calculated power dissipation requires the use of a large resistor, or several devices
have to share the same resistor, then ST suggests using
Solution 2: a diode (D
A resistor (R
inductive load. This small signal diode can be safely shared amongst several different HSD.
Also in this case, the presence of the ground network produce a shift (~600 mV) in the input
threshold and the status output values if the microprocessor ground is not common with the
device ground. This shift does 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.

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