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 w ill 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 Dw ell timer is included in the
FGBS3040E1-F085 w hich w ill 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 Dw ell timer is exceeded, the
FGBS3040E1-F085 w ill enter a Soft-Shut-Dow n mode
(SSD) slow ly dropping the collector current thereby
discharging the coil such as to inhibit a spark event.
Once the soft shutdow n operation has started, any
transitions on the input signal are ignored until after
completion of the soft shutdow n function. The
FGBS3040E1-F085 w ill also limit the collector current of
the IGBT to Ic(lim) during charging.
