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