DESCRIPTION
The VB927T is a monolithic high voltage integrated circuit
made by using the STMicroelectronics VIPowerâ¢
technology, which combines vertical current flow power
trilinton with a coil current and a collector voltage
clamping. The device is particularly suitable for
application in high performance electronic car ignition,
where coil current limitation and voltage clamping are
required.
