A*STAR to co-develop high precision temperature sensor ASIC with leading automotive solutions company for tire pressure system

Singapore’s A*STAR Institute of Microelectronics (IME) is partnering with a leading multi-national company in automotive solutions to develop a high accuracy temperature sensor integrated circuit block for automotive and industrial applications. The temperature sensor will be part of a tire pressure monitoring system (TPMS) which maintains the correct tire pressure for comfortable driving, fuel efficiency, longer tyre-life and higher safety for the driver.

The employment of a TPMS can reduce road accidents, fuel consumption and CO2 emissions.

The accuracy of TPMS is affected by the change of temperature. Current temperature sensor accuracy is on the order of +/-3 °C, which limits the performance and safety feature of TPMS. Using 0.13 µm CMOS technology, IME and the industry partner will work together on the design of a new temperature sensor IC for TPMS to dramatically improve the accuracy down to +/-0.5 °C. With the substantial improvement in temperature sensor accuracy, the TPMS will have greater capacity to pre-empt and react to enhance safety for the driver.

This project is facilitated through the A*STAR Capabilities for Automotive Research (A*CAR), an A*STAR initiative to bring together automotive OEMs, suppliers and the R&D community to work hand in hand in addressing key research areas in automotive technologies. The A*CAR Consortium was launched on 30 September 2008 with the partnership of Bosch, Dou Yee and Infineon. The Consortium draws on the collective expertises from the 7 research institutes under Science and Engineering Research Council (SERC). There are currently 14 companies on-board collaborating on 16 multi-disciplinary projects.
