PRINCIPLE OF OPERATION
The
VB029, VB029SP, VB029(011Y)
VB029(012Y) are mainly intended as high voltage
power switch device driven by a logic level input and
interfaces directly to a high energy electronic ignition coil.
The input V
VB029(012Y) are fed from a low power signal
of theVB029, VB029SP,VB029(011Y)
IN
generated by an external controller that determines both
dwell time and ignition point. During V

high (≥4V) the
IN
increase current in the coil to the desired, internally set
current level.
When the collector current exceeds 4.5A, the diagnostic
signal is turned high and it remains so, until the load
current reaches 5.8A (second threshold). At that value,
the diagnostic signal is turned low, and the µC forces the
V
to the low state. Duringthe coil current switch-off, the

level is reached, forces the darlington (using the “Driver”
block) to limit the current provided.
The transition from saturation to desaturation, coil current
limiting phase, must have the ability to accommodate an
overvoltage. A maximum overshoot of 20V is allowed.
There can be some short period of time in which the
output pin (HV
current due to leakage inductances and stray
) is pulled below ground by a negative
C
capacitances of the ignition coil. Thiscan cause parasitic
glitches on the diagnostic output.
VB029, VB029SP,
VB029(011Y) VB029(012Y) have a built-in protection
circuit that allows to lock thep-buried layerpotential of the
linear stage to the collector power, when the last one is
pulled underground.
FIGURE 1: Application circuit
THERMAL BEHAVIOUR
You can see in the block diagram of the
VB029SP, VB029(011Y) VB029(012Y)
overtemperature protection. The purpose of this circuit is
to shift the current level at which the first diagnostic is
activated down of about 1A.
This information can be managed by the micro that can
take the corrective action in order to reduce the power
dissipation. This block is not an effective protection but
just an overtemperature detection. The shift down of the
first flag level cannot be present for temperatures lower
than 125°C.
As an example of its behavior you can suppose a very
simple motor management system in which the micro
does justa simple arithmetic calculation to decide when to
switch-off the device after the first flag threshold.
EXAMPLE:

As soon as the temperature rises over the overtemp
threshold, the first diagnostic is shifted down to about
1.5A and, in this example, the switch-off current will be
