DESCRIPTION
The VB125SP is a high voltage power integrated
circuit
made
using
Microelectronics
Vertical
Technology,
with vertical current flow power
darlington and
logic level compatible driving
circuit.
The VB125SP can be directly biased by using the
12V battery voltage, thus avoiding to use a low
voltage regulator. It has built-in protection circuits
for coil current limiting and collector voltage
clamping. It issuitable as smart, highvoltage, high
current interface in advanced electronic ignition
system.
