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
maximum on-state currents of the different devices.
Please note that if the microprocessor ground is not shared by the device ground then the
R
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).
