Numerous Protection Features
Brief Functional Description (E525.01)
Features (E525.01)
Brief Functional Description (E910.89)
The E525.01 is a low-cost control IC for use in a spark plug
ignition circuit for petrol engines. Together with an insulated gate
bipolar transistor (IGBT) the IC controls the energy in a pencil coil
used to trigger the ignition spark. Only a few external components
are needed for the complete electronic circuit, which can be
closely integrated to the spark plug device by this. The IC is controlled
by a digital signal at IN coming from an ECU. The device provides the
gate drive current to the IGBT and the necessary protection at output
GATE. Additional protection features of this IC include “soft start-up”
(SSU) and “soft shut-down” (SSD).
SSU limits the rate of change of the IGBT collector current during
increase of magnetic energy in the primary coil. This measure
will avoid unwanted ignition sparks due to too high voltage
induction during current ramp-up. It allows for saving of high
voltage protection diodes in the (secondary) output branch of
the ignition coil. SSD is a protection function which allows to
shut-off smoothly the collector current without inducing high
voltage for spark generation in the secondary coil, in case no
switch-off command was received at IN from the ECU after an
allowed maximum on-time.
ƒƒ Slew controlled gate drive of IGBT
The IC E910.89 is intended for use in encapsulated automotive
ignition systems. It is mounted directly together with the ignition
coil to a compact module.
Corresponding to an input control signal the IC drives an IGBT,
which provides the current to the ignition coil. An internal
slew-rate control and programmable soft turn-on and soft
switch-off functions ensure well defined timing of the ignition
event and shall prevent IGBT and coil from overloads.
The high circuit integration reduces the number of components
for minimum sized electronics.
ƒƒ Soft switch-on of primary coil current
ƒƒ Self timed soft shut-down to prevent destruction
of coil or IGBT due erroneous control input
ƒƒ Ground shift tolerant input: ±1.5 V
ƒƒ Compact assembly close to pencil coil due to few components
ƒƒ Supply voltage: 5.5V to 28V
ƒƒ Operating temperature range -40°C to +140°C
ƒƒ Qualified according to AEC-Q100
ƒƒ SOIC8N package
