DESCRIPTION

The VB027ASP is a high voltage power

integrated circuits made using STMicroelectronics

Vertical Intelligent Power Technology, with

vertical current flow power darlington and logic

level compatible driving circuits.

Built-in protection circuits for coil current limiting

and collector voltage clamping allows the

VB027ASP to be used as a smart, high voltage,

high current interface in advanced electronic

ignition systems.
