DESCRIPTION

The VB927T is a monolithic high voltage integrated circuit

made by using the STMicroelectronics VIPower™

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.
