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.
