DESCRIPTION

The VB923 is a monolithic high voltage integrated

circuits made using STMicroelectronics VIPower

Technology, which combines a vertical current

flow power trilinton with a coil current limiting

circuit and a collector voltage clamping.

The device is peculiarly suitable for application in

high performance electronic car ignition, where

coil current limitation and voltage clamping are

required.
