DESCRIPTION

The VB125ASP is a high voltage power integrated

circuit made using the STMicroelectronics

VIPower™ M1-2 technology, with vertical current

flow power darlington and logic level compatible

driving circuit. The VB125ASP can be directly

biased by using the 12V battery voltage, thus

avoiding to use a low voltage regulator. It has

built-in protection circuit for coil current limiting

and collector voltage clamping. It is suitable as

smart, high voltage, high current interface in

advanced electronic ignition system.
