vn5012ak-e application information doc id 13240 rev 8 21/30 3.1.2 solution 2: a diode (d gnd ) in the ground line a resistor (r gnd =1 k ) 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 ground network produces a shift ( 600 mv) in the input threshold and in the status output values if the microprocessor ground is not common to the device ground. this shift does not vary if more than one hsd shares the 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 7637-2: 2004(e) 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 are pulled negative. st suggests to insert a resistor (r prot ) in line to prevent the c i/o pins from latching-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 compatibility) with the latch-up limit of c i/os. -v ccpeak /i latchup r prot (v oh c -v ih -v gnd ) / i ihmax calculation example: for v ccpeak = -100 v and i latchup 20 ma; v oh c 4.5 v 5k r prot 180 k . recommended values: r prot =10k , c ext =10nf.
