33814

Freescale Semiconductor Product Preview Document Number: MC33814 Rev. 1.0, 8/2012 Two Cylinder Small Engine Control IC 33814 The 33814 is an engine control analog power IC intended for two cylinder motorcycle and other small engine control applications. The IC consists of TWO CYLINDER SMALL ENGINE CONTROL IC six integrated low side drivers, three pre-drivers, a Variable Reluctance Sensor (VRS) input circuit, a voltage pre-regulator using an external pass transistor, and two 5 volt internal regulators, one for the microcontroller unit (MCU) VCC supply, and one for use as a protected sensor supply. Also included is an MCU reset control circuit with watchdog, an ISO 9141 K-Line interface for diagnostic communication and a Serial Peripheral Interface (SPI). The six low side drivers are intended for driving two fuel injectors, a lamp, two relays or other loads, and a tachometer. The pre- drivers are intended to drive IGBT or MOSFET transistors to control ignition coils, an...
