HIGH VOLTAGE IGNITION COIL DRIVER
POWER I.C.
n NO EXTERNAL COMPONENT REQUIRED
n INTEGRATED HIGH VOLTAGE CLAMP
n COIL CURRENT LIMIT INTERNALLY SET
n HIGH RUGGEDNESS
DESCRIPTION
The VB921ZVFI, VB921ZVSP is a monolithic high
voltage
integrated
circuit
made
using
the
STMicroelectronics VIPower™ 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.
