DESCRIPTION

The VB027SP 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, highvoltage, high current interface in advanced electronic ignition system.
