The VB125SP is a high voltage power integrated circuit made using SGS-THOMSON Microelectronics Vertical Intelligent Power Technology, with vertical current flow power darlington and logic level compatible driving circuit.
The VB125SP can be directly biased by using the 12V battery voltage, thus avoiding to use a low voltage regulator. It has built-in protection circuits for coil current limiting and collector voltage clamping. It is suitable as smart, high voltage, high current interface in advanced electronic ignition system.
