FGBS3040E1-F085 — Integrated Smart Ignition Coil Driver April 2016 FGBS3040E1-F085 Integrated Smart Ignition Coil Driver Features  400V 300mJ N Channel Ignition IGBT  Control Input buffering  Input spike filter of typical 13us  Operation from Ignition or Battery line  Ground shift tolerance +/- 1.5V  Programmable maximum dw ell time  Current programmable bidirectional Input/Diagnostic pin  Collector Current limit typical 16.5A  Soft Shutdow n of Collector Current after Max Dw ell Applications  Coil on Plug Ignition systems  General ignition systems 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 droppin...
