DESCRIPTION
The VB025SP is a high voltage power integrated
circuit made using STMicroelectronics VIPower
Technology, with vertical current flow power
darlingtonandlogiclevelcompatibledrivingcircuit.
Built-in protection circuits for coil current limiting
and collector voltage clamping allows the
VB025SP to be used as a smart, high voltage,
high current interface in advanced electronic
ignition systems.
