Description
The FGBS3040E1_F085 is designed to directly drive an
ignition coil and control the current and spark event of
the coil. The coil current is controlled via the
input/diagnostic pin. When the input is driven high, the
IGBT is enabled to start charging the coil. The
FGBS3040E1_F085 will sink a current (IIN1) into the
input to denote this condition. When the collector current
increases to Icthr the input current into the
FGBS3040E1_F085 is reduced to IIN2 indicating the
collector current has reached this level. An input filter
suppresses input signals of less then 13 µsec in
duration. A Max Dwell timer is included in the
FGBS3040E1_F085 which will turn off the IGBT if the
input stays active for longer then the programmed time.
This time interval can be modified through an external
capacitor. When the Max Dwell timer is exceeded, the
FGBS3040E1_F085 will enter a Soft-Shut-Down mode
(SSD) slowly dropping the collector current 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
FGBS3040E1_F085 will also limit the collector current
of the IGBT to Ic(lim) during charging.
