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.
The VB027ASP is a high-voltage power integrated circuit designed for advanced electronic ignition systems. It utilizes Vertical Intelligent Power Technology with vertical current flow power darlington and logic-level compatible driving circuits to interface directly with high-energy ignition coils.
The device includes built-in protection circuits for coil current limiting and collector voltage clamping, allowing it to function as a smart, high-voltage, high-current interface. Key features include an internally set primary coil voltage of 345V and an internally set coil current limit.

Yes, the driving current is quasi-proportional to the collector current.
The diagnostic output goes high when the collector current exceeds 3 A.
The primary voltage is typically clamped to 345 V when switching off the coil.
