DESCRIPTION
The VB927 is a monolithic high voltage integrated
circuit made using STM 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.
