Scandmec AB in Mullsjö, Sweden, manufactures seat heaters and other automotive components for car and seat manufacturers. They have a very large market share for seat heaters controlled by a thermostatic device. The market does move towards electronically controlled heaters and grows fast as larger markets demands seat heaters as standard. Scandmec's current solution for the electronically controlled seat heater is based on a bipolar analog array with several external components. It has limitations in flexibility of controlling and does not fulfil all the current demands of safety and reliability. The main reason to develop the new ASIC is the hard safety regulations that is set to new automotive products. The new solution is a mixed-signal smart-power ASIC. Very few external components are needed and the functions and flexibility are considerably enhanced. The new ASIC results in a product that is smaller, lighter, more reliable and less expensive than the earlier solution. With this experiment, Scandmec have gained experience in system knowledge, mixed-signal and smart-power ASIC design principles and flow. They also learned how to manage and control this kind of project with an ASIC supplier. The new product will have a payback period of less than 6 months and a ROI (Return on investment) more than 300%. The cost to develop prototypes for the new product was 150KECU. The project started in November 1996 and ended in December 1997. TTN: IMC/SGA

Detailed information

You can also benefit from microelectronics

Mixed signal ASIC technology provided Kongsberg Automotive AB with the means of improving its products and enhancing its market position. You can also achieve significant benefits by acquiring the right microelectronics technology and utilising it in your product or manufacturing process. You can get help from FUSE to realise this.

FUSE is a technology transfer programme, funded by the European Commission to stimulate the wider use of microelectronics technologies by European enterprises to increase their competitiveness and enhance their economic growth. The demonstrator described here is one of many examples in the public FUSE portfolio covering the whole spectrum of microelectronics technologies and spanning a wide range of applications and industry sectors.

FUSE provides you with:

  • Best practice in acquiring specific microelectronics technologies and conducting full development projects through the FUSE portfolio of real life demonstrator documents.
  • Local training and expert support to plan your innovation realistically and help you conduct your project successfully.
