This resistor can be shared amongst several different HSDs. Please note that the value of
this resistor should be calculated with formula (1) where I

Please note that if the microprocessor ground is not shared by the device ground then the

values. This shift will vary depending on how many devices are ON in the case of several
high-side drivers sharing the same R
If the calculated power dissipation leads to a large resistor or several devices have to share
the same resistor then ST suggests to utilize Solution 2 (see below).
