DESCRIPTION
The VB325SP is a high voltage power integrated
circuit made us ing the STMicroelectronics
VIPower™ M1-3 technology, with vertical current
flow pow er dar lington and logic l evel compatible
driving circuit. The enable pin allows to externally
block the s witch when the i nput i s on. B uilt-in
protection c ircuit for c oil c urrent limiting a nd
collector voltage clamping allows the device to be
used as smart, high voltage, high current interface

in advanced electronic ignition system. If the input
signal from the micro happens to remain high, the
device pr otects i tself ag ainst ov er-heating by
forcing collector current to s mooth decrease (low
voltage clamp feature) and no und esidered spark
occurs (see figure 4).

PRINCIPLE OF OPERATION
The VB325SP is mainly intended as a high voltage
power switch dev ice driven by a l ogic l evel i nput
and interfaces directly to a high energy electronic
ignition coil.
The i nput V IN o f the V B325SP i s fed from a l ow
power s ignal gener ated by an ex ternal c ontroller
that determinesboth dwell time and ignition point.
During V in hi gh ( ≥ 4V) t he V B325SP increases
current i n t he c oil t o t he desired, internally s et
current level.
After re aching this level, the coil current remains
constant until th e ignition point, that corresponds
to the t ransition of Vin from high to low (typ. 1.9V
threshold).
During the coi l curre nt sw itch-off, the p rimary
voltage HVC is clamped at an i nternally set value
Vcl, typically 380V. The transition from saturation
to de saturation, c oil c urrent l imiting p hase, m ust
have the ability to accomodate an overvoltage.
A maximum overshoot of 20V is allowed.
FEEDBACK
When th e c ollector c urrent ex ceeds 4.5A , t he
feedback signal is turned high and it remains so,
until the input voltage is turned-off.
OVERVOLTAGE
The V B325SP c an w ithstand the f ollowing
transients of the battery line:
-100V/2msec(Ri =10 Ω)
+100V/0.2msec (Ri =10 Ω)
+50V/400msec (Ri = 4.2 Ω, with VIN= 3V)
