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 drive
