The IC E910.89 in intended for use in encapsulated automotive ignition systems. It is mounted directly together
with the ignition coil to a compact module.
Slew rate controlled gate drive voltage for IGBT
Soft turn-on function
Soft switch-off function with safety timer
Differential input for optimum suppression
of ground shift disturbances
Integrated power-on reset
Supply voltage range 6V to 26V
Operating temperature range – 40°C to + 140°C
SOIC 8N package
Corresponding to an input control signal the IC drives
an IGBT, which provides the current to the ignition coil.
An internal slew-rate control and programmable soft
turn-on and soft switch-off functions ensure well defined timing of the ignition event and shall prevent
IGBT and coil from overloads. The high circuit integration reduces the number of components for minimum
sized electronics.
