DESCRIPTION

The VB027, VB027(011Y), VB027(012Y) is a high voltage power integrated circuit made using the STMicroelectronics VIPower technology, with vertical current flow power darlington and logic level compatible driving circuit. 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.
