Description

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.

Features

■ Signal Line Input Buffer

■ Input spike filter

■ Operation from Ignition or Battery line

■ Ground shift tolerance +/- 1.5 V

■ Programmable maximum dwell time

■ Programmable Input Pull down current

■ Control IGBT current limiting through Vsense pin

■ Soft Shutdown following Max Dwell Time out

Applications

■ The FAN1100-F085 is an advanced Ignition IGBT

control IC available in a SO8 package or die sales.

This full featured Smart Ignition IGBT Driver is

particularly advantageous in “switch on coil”

applications where size and system performance of

the ignition driver are important.
