STMicroelectronics VB927FI
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. For higher temperature, the thermal protection circuit will begin its action reducing the Icl limit according with the power dissipation.| Part No. | VB927FI |
