IGNITION GATE DRIVER IC

DESCRIPTION

The UTC UC1010 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 of the UTC UC1010 is driven high, the output

is enabled, the IGBT will be turned on and start charging the coil.

The UTC UC1010 will sink a current (IIN) into the input pin based

on programmed current on the RA line.
