vnq5027ak-e application information doc id 12730 rev 6 21/31 3.1.2 solution 2: a diode (d gnd ) in the ground line a resistor (r gnd = 1k ) should be inserted in parallel to d gnd if the device drives an inductive load. this small signal diode can be safely shared amongst several different hsds. also in this case, the presence of the grou nd network will produce 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 will not vary if more than one hsd shares t he same diode/resistor network. 3.2 load dump protection d ld is necessary (voltage transient suppressor) if the load dump peak voltage exceeds the v cc max dc rating. the same applies if the device is subject to transients on the v cc line that are greater than the ones shown in the iso t/r 7637/1 table. 3.3 mcu i/os protection if a ground protection network is used and negative transients are present on the v cc line, the control pins will be pulled negative. st suggests to insert a resistor (r prot ) 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 c and the current required by the hsd i/os (input levels compatibilit y) with the latch-up limit of c i/os. -v ccpeak /i latchup r prot (v ohc -v ih -v gnd ) / i ihmax calculation example: for v ccpeak = - 100v and i latchup 20ma; v ohc 4.5v 5k r prot 180k . recommended values: r prot = 10k , c ext = 10nf .
