Reduce emissions and improve efficiency for direct fuel injection engines with Freescale programmable solenoid controller
January 17, 2014 ā Governments worldwide have issued regulations requiring automakers to improve fuel efficiency and meet new emissions standards over the next five to ten years.
To help automakers and their suppliers comply with these requirements, Freescale Semiconductor today announced the MC33816 programmable solenoid controller, designed to reduce emissions and improve fuel efficiency for both gasoline and diesel direct fuel injection engines. The flexible architecture is also applicable for driving dual clutch transmissions, as well as precision solenoids in factory automation applications.
The deviceās functional integration enables substantial bill-of-materials reductions, and provides the flexibility and scalability necessary to be easily integrated into virtually any engine system, including gasoline, diesel, flex-fuel and even LNG engines, regardless of the number of cylinders.
āIncreasingly stringent fuel efficiency standards require highly advanced analog technologies like the intelligent MC33816 device,ā said James Bates, senior vice president and general manager for Freescaleās Analog and Sensors business. āThis new programmable solenoid controller can help automotive OEMs and their suppliers meet efficiency and emissions goals, while providing a reliable, high-performance system solution that supports advanced diagnostic functionality, faster response times, and optimal programmability.ā
The intelligent MC33816 controller additionally provides embedded encryption and microcode protection to inhibit reverse engineering and help safeguard system IP and software.
Additional features include:
- 9-32 V continuous supply, 5.5-58 V transient
- Up to 72 V pre-driver operating range
- Precision peak and hold drive capability
- Integrated DC-DC boost converter control circuitry
- Choice of four programmable slew rates 12.5 V/uS ā 300 V/uS
- 10 x 10 mm 64-pin LQFP-EP package
Freescale provides hardware and software to support the MC33816 programmable solenoid controller. The KIT33816AEEVM evaluation board allows utilization of the controllerās functions and is available now at www.freescale.com/KITMC33816 for a price of $216 (USD).
