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.
