MC33814FS, Two Cylinder Small Engine Control IC
Freescale Semiconductor Inc.
The 33814 is an engine control analog power IC intended for two cylinder motorcycle and
other small engine control applications. The IC consists of 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 MCU VCC
supply and the other 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, and a HEGO heater.
The device is packaged in a 48 pin LQFP with an exposed pad.
