产品概述

描述

L9177 is a device realized in ST BCD proprietary technology, able to provide the full set of power supplies and signal preprocessing peripherals needed to control a 2 Cylinder internal combustion Engine for Low End Application (e.g. small motorcycle, K-car, nautical engines, etc.). L9177 integrates a 5 V main voltage regulator, a 5 V 40 mA tracking regulator for sensor supply and a 2.5 mA 5 V standby regulator.
The two channels injector drivers, the O2 sensor heater and two relay drivers can be controlled both with parallel input and with SPI interface. One additional relay driver and the lamp driver are controlled by SPI. The stepper motor driver is designed for a double winding coil motor, used for engine idle speed control.
Low side drivers implement SR control to minimize emission.
A protected 50 mA high side driver is provided.
A Variable Reluctance Sensor interface allows the connection to a commercial magnetic pick-up, allowing the indirect measurement of internal combustion engine crank angle. A K-line (standard ISO-9141 compatible) is provided as data communication interface.
All functionalities are fully protected and provide complete diagnostics via a 24bit SPI interface. An overall protection against over temperature is provided as well.
The device is available in PowerSO46, ST proprietary package for high power application.
