10/18 VNQ600A m c 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 m c i/os pins to latch-up. the value of these resistors is a compromise between the leakage current of m c and the current required by the hsd i/os (input levels compatibility) with the latch-up limit of m c i/os. -v ccpeak /i latchup r prot (v oh m c -v ih -v gnd ) / i ihmax calculation example: for v ccpeak = - 100v and i latchup 3 20ma; v oh m c 3 4.5v 5k w r prot 6k w . recommended r prot value is 5k w. 0246810121416 3000 3500 4000 4500 5000 5500 6000 6500 min.tj=-40c max.tj=-40c min.tj=25...150c max.tj=25...150c typical value figure 3: i out /i sense versus i out i out /i sense i out (a)
