ELECTRICAL CHARACTERISTICS

PRINCIPLE OF OPERATION
The VB025SP is mainly intended as a high
voltage power switch device driven by a logic
level input and interfacesdirectly to a high energy
electronicignition coil.
The input Vin of the VB025SP is fed from a low
power signal generated by an external controller
that determinesboth dwell time and ignition point.
During Vin high (
≥
4V) the VB025SP increases
current in the coil to the desired, internally set
current level.
After reaching this level, the coil current remains
constant until the ignition point, that corresponds
to the transition of Vin from high to low (typ. 1.9V
threshold).
During the coil current switch-off, the primary
voltage HVc is clamped at an internally set value
Vcl, typically380V.
The transitionfrom saturation to desaturation,coil
current limiting phase, must have the ability to
accomodate
an
overvoltage.
overshootof 20V is allowed.
FEEDBACK
When the collector current exceeds 4.5A, the
feedback signal is turned high and it remains so,
until the input voltage is turned-off.
OVERVOLTAGE
The
VB025SP can
withstand the
transientsof the battery line:
