Applications
The FAN1100_F085 is an advanced Ignition IGBT
control IC available in a SO8 package or die sales.
This full featured Smart Ignition IGBT Driver is
particularly advantageous in “switch on coil”
applications where size and system performance of
the ignition driver are important.
Description
The FAN1100_F085 is designed to directly drive an
ignition IGBT and control the current and spark event of
the coil. The coil current is controlled via the input pin.
When the input is driven high, the output of the
FAN1100_F085 is enabled to turn on the IGBT and start
charging the coil. The FAN1100_F085 will sink a current
(IIN) into the input pin based on programmed current on
the RA line.
An input spike filter suppresses input signals of less
then 13 µsec in duration. A Max Dwell timer is included
in the FAN1100_F085 which will turn off the IGBT if the
input stays active for longer than the programmed time.
This time interval can be modified through an external
capacitor on the CSSD pin. When the Max Dwell timer
is exceeded, the FAN1100_F085 will enter a Soft-Shut-
Down mode (SSD) slowly dropping the collector current
by lowering the gate drive to the IGBT thereby
discharging the coil such as to inhibit a spark event.
Once the soft shutdown operation has started, any
transitions on the input signal are ignored until after
completion of the soft shutdown function. The
FAN1100_F085 will also limit the collector current of the
IGBT to Ic(lim) during charging. This again is done
through the sense resistor in the emitter leg of the
Ignition IGBT developing a signal input to the Vsense
pin of the FAN1100_F085.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.
