DESCRIPTION
The VB326SP is a high voltage power integrated
circuit made using the STMicroelectronics
VIPower™ M1-3 technology, with vertical current
flow power darlington and logic level compatible
driving circuit. The enable pin allows to externally
block the switch when the input is on. Built-in
protection circuit for coil current limiting and
collector voltage clamping allows the device to be
used as smart, high voltage, high current interface
in advanced electronic ignition system. If the input
signal from the micro happens to remain high, the
device protects itself against over-heating by
forcing collector current to smooth decrease (low
voltage clamp feature) and no undesidered spark
occurs (see figure 4).
