VNQ5E160AK-E application information 25/37 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 s(on)max becomes the sum of the 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 gnd will produce a shift (i s(on)max * r gnd ) in the input thresholds and the status output values. this shift will vary depending on how ma ny devices are on in the case of several high side drivers sharing the same r gnd . if the calculated power dissipation leads to a large resistor or several devices have to share the same resistor then st suggests to utilize section 3.1.2: solution 2 : diode (dgnd) in the ground line . 3.1.2 solution 2 : 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 7637-2: 2004(e) table. 3.3 mcu i/os protection if a ground protection network is used and negative transient 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/o s (input levels compatibility) with the latch-up limit of c i/os: equation 2 -v ccpeak /i latchup r prot (v oh c -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.
