STMicroelectronics VB922

The VB922 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.
