DESCRIPTION

B uilt-in protection c ircuit for c oil c urrent limiting a nd collector voltage clamping allows the device to be used as smart, high voltage, high current interface BLOCK DIAGRAM VCC 10 1 PowerSO-10™ in advanced electronic ignition system. If the input signal from the micro happens to remain high, the device pr otects i tself ag ainst ov er-heating by forcing collector current to s mooth decrease (low voltage clamp feature) and no und esidered spark occurs (see figure 4).
