Solution 2: A diode (D
A resistor (R
D
This small signal diode can be safely shared amongst
several different HSD. Also in this case, the presence of
the ground network will produce a shift (j600mV) in the
input threshold and the status output values if the
microprocessor ground is not common with the device
ground. This shift will 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.
LOAD DUMP PROTECTION

The same applies if the device will be subject to
transients on the V

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

OPEN LOAD DETECTION IN OFF STATE
Off state open load detection requires an external pull-up
resistor (R
positive supply voltage (V
supply the microprocessor.
The external resistor has to be selected according to the
following requirements:
1) no false open load indication when load is connected:
2) no misdetection when load is disconnected: in this
Because I
pulled high (up to several mA), the pull-up resistor R
should be connected to a supply that is switched OFF
when the module is in standby.
