Solution 2: diode (D
A resistor (R
inductive load.
This small signal diode can be safely shared amongst several different HSDs. Also in this
case, the presence of the ground network produces 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 not varies 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.

Microcontroller I/Os protection
If a ground protection network is used and negative transient are present on the V
the control pins is pulled negative. ST suggests to insert a resistor (R
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.

Open-load detection in off-state
Off-state open-load detection requires an external pull-up resistor (R
output pin and a positive supply voltage (V
microprocessor.
The external resistor has to be selected according to the following requirements:
