&& PREVIOUS FINALIST | MAIN | NEXT FINALIST >> Category: Analog: Front-End ICs Finalist: MC33812 small-engine analog IC, Freescale Semiconductor  In order to satisfy stringent exhaust emission levels, Asian manufacturers are beginning to replace traditional me-chanical carburetors with electronic controls to incorporate fuel injection or e-carb systems. The MC33812 integrated analog circuit combines these functions. It provides the interfaces between the microcontroller and external engine devices such as the fuel injector, relay, ignition spark coil, malfunction indicator lamp, battery, and diagnostic equip-ment. The MC33812 integrates the power supply regulator for the MCU, the reset and the watchdog functions, a serial IS09141 interface for diagnostic communication, an ignition predriver, an injector driver, and two additional low-side drivers that can be used for driving a relay or second injector and a malfunction indicator lamp. Freescale simultane-ously introduced a comprehensive reference design with board, software, and examples to shorten the time required to develop the electronic control. |
