DESCRIPTION
The VB921ZVFI, VB921ZVSP is a monolithic high
voltage integrated circuit made using the
STMicroelectronics VIPower鈩?M1-2 technology,
which combines a vertical current flow power
trilinton with a coil current limiting circuit 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.
