Freescale Semiconductor Advance Information Document Number: MC33812 Rev. 5.0, 7/2010 Multifunctional Ignition and Injector Driver The 33812 is an engine control analog power IC intended for motorcycle and other single/dual cylinder small engine control applications. The IC consists of three integrated low side drivers, one pre-driver, a +5.0 V, voltage pre-regulator, an MCU watchdog circuit, an ISO 9141 K-Line interface, and a parallel interface for MCU communication. The three low side drivers are provided for driving a fuel injector, a lamp or LED, and a relay or other load. The pre-driver is intended to drive either an Insulated Gate Bipolar Transistor (IGBT) or a bipolar Darlington transistor to control an ignition coil.
