Ignition Gate Drive IC
FAN1100-F085
Description
SOIC8
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 ms 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

Applications
The FAN1100−F085 is an advanced Ignition IGBT control IC

Ignition IGBT Driver is particularly advantageous in “switch on coil”
applications where size and system performance of the ignition driver
are important.

typical 1.5 A/ms. (Based on ISL9V3040 Ignition IGBT). If
a valid falling edge is received after the time TDMAX, the

completed. The IGBT cannot be subsequently turned on
until a valid rising edge is detected.
If the CSSD capacitor has a value below 2.2 nF or the
CSSD pin is shorted to ground, the maximum dwell time and

started. If a valid falling edge has not been received after the
