VB923
HIGH VOLTAGE IGNITION COIL DRIVER
POWER IC
s NO EXTERNAL COMPONENT REQUIRED
s INTEGRATED HIGH VOLTAGE CLAMP
s COIL CURRENT LIMIT INTERNALLY SET
s HIGH RUGGEDNESS
DESCRIPTION
The VB923 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.
