PowerSO-10
The VBG15NB22T5SP-E is an ignition coil driver
made by using the latest high voltage
Powermesh™ technology based on patented strip
lay-out.
(s)
The device is particularly suitable in high
performance car ignition, where coil current
limitation and precise voltage clamping are
required with no external component. ESD is an
additional inherent features.

The VBG15NB22T5SP-E has a timer block built-in (see Figure 8), in order to have a soft
switch-off of the device. When an input signal is provided to the device (see Figure 7, case
a), the external capacitor starts its charging through the Switch1 (with a slope depending on
VCC) and goes on until it reaches the Vref voltage (see Figure 7, case b). As soon as it
happens, the voltage comparator gives an enable signal (see Figure 7, case c) that
develops different functions:
s
b
O
10/16
●
It opens Switch1 and closes Switch2, so that the external capacitor discharges.
●
It provides power to the transconductance inverting amplifier, the input of which is
theexternal capacitor voltage.
It means that while VC decreases, Itimer (see Figure 7, case d) increases proportionally. The
increasing drop voltage on RO, due to Itimer, has to be compensated by a reducing drop
voltage on RSENSE, so to maintain the A input voltage equal to the B one. Since the RSENSE
drop depends on the coil current, it means that a soft decreasing of it occurs (see Figure 7,
case e).
