| Summary | |
| The project consists of developing fully integrated
high-voltage micro-motor driver ICs for two different electromagnetic micro-motors
which are dedicated for satellite applications. Each die will be packaged
in the corresponding micro-motor. The systems must operate at 200°C
under a 30V power supply and must survive space irradiation. Both integrated
circuits use the same core unit to control the speed of the motors, but
differs in the sensing operation. In one case, the speed is sensed with
a Hall-effect sensor, while in the second case, a complex signal processing
logic emulates the lack of a physical sensor. However, both applications
make use of the same specific mixed-signal library blocks developed within
the framework of this project, and since the complex signal processing
logic already exists, no additional efforts are required to implement the
sensorless solution.

| Main Objectives | |
| The objective of this project is to develop two challenging
industrial demonstrators pointing out some unique characteristics of thin-film
Silicon-On-Insulator (SOI) technologies for critical high-temperature /
high-voltage mixed-signal applications. As a matter of fact, thanks to
the full-dielectric isolation of SOI technologies, a number of significant
advantages are offered in comparison to classical Silicon bulk technologies.
Among these special features, the excellent temperature behaviour up to
300°C, the intrinsic immunity against latch-up and the increased circuit
density provided by SOI should be pointed out. Moreover, the proposed technology
offers complementary high-voltage features, up to 100V, that extend the
use of SOI to the field of high-voltage integrated circuits (ICs).
Design methodologies for high-temperature and high-voltage SOI mixed-signal IC's, as well as circuit libraries issued from this project cover potential fields of applications that extend much beyond the aerospace industry. The automotive industry is among the first candidates, particularly for some electronic circuit functions located in the vicinity of the engine block and must operate at in a high-temperature / high-voltage environment. Similar operating conditions can be found in other application fields such as nuclear reactors and military electronics, where a reduced sensitivity to irradiation is required additionally. Without being exhaustive, other application fields for SOI technologies can be found in petrol drilling, railways, avionics and electric power conversion industries. |
