Concept of hierarchical control with the continuous development of the intelligent charging and increasing demand for sensors and SoC product because of its cost, the advantage of little small, the solution is to fit the program development. Infineon Technologies (China) Limited automotive electronics business, said Li Shiming, Senior Marketing Engineer “a new generation of Infineon SP37 Tire Pressure Monitoring System (TPMS) single-chip solution to comply with this trend, the controller unit detection, an RF transmitter, low frequency power modules and power receiver integrated in a chip, the requirement of auto-on-chip “.

TPMS is a comparison of speculation in the Chinese market a concept of fire, but so far only the United States is the law enforcement world countries TPMS. Since September 2007, all U.S. after Sell The maximum design weight not exceeding 4536 kg in total of four cars and commercial vehicles are required to install TPMS. Although the voice of TPMS in China has been a long time, but the standard is postponed again and again, the current application is limited only to certain high-end models, but these did not prevent the semiconductor manufacturers drivers-a huge investment in this area.

The industry agrees that the following TPMS transmitter module is highly integrated, single management passivity wireless. TPMS with IC market on the high integration and high reliability requirements, it is currently testing the physical requirements of MEMS sensor with triple the microcontroller, RF module of the next generation of TPMS sensor. Such as TPMS solution Freescale MPXY8300, is the capacitive pressure sensor, temperature sensor components, MCU, RF, acceleration sensors and an alarm function of the interface circuit, all integrated into one chip, and uses Freescale’s ultra-small package (SSOP). Ultra-small size and improved protective function of the media makes the program particularly suited to the tire valve or install.

concept of hierarchical control with the continuous development of the intelligent charging and increasing demand for sensors and SoC product because of its cost, the advantage of little small, is the solution to accommodate this development program. Infineon Technologies (China) Co., Ltd. Main unit of car electronics marketing company engineer, said Li Shiming, “Infineon SP37 Tire Pressure Monitoring System the new generation (TPMS) single-chip solution to comply with this trend, the controller , the detection unit, RF transmitter, receivers and low-frequency power supply built into a chip inside, reached car-on-chip requirements. “

The car design for accuracy management is an important factor, Infineon success of giant magnetoresistance (GMR) integration in standard CMOS semiconductor manufacturing process. “In the electric power steering system, the Infineon technology-based integrated GMR (IGMR) of the sensor chip set technology-based and smart linear Hall effect sensor can be perfect to achieve the perception of the angle steering and torque. ” Shiming Li said. Infineon’s sensors can accurately measure the 0 to 360 abnormal steering angle, has two full-bridge GMR, a temperature sensor, two ADCs, a number of regulators, filters, and execute the process can follow permanently the internal mechanism of these components. TLE5010 angle sensor chip with two digital components? Sine and cosine functions. Sensor through the SPI interface, 8-bit microcontroller to use these components to calculate the actual angle of the signal.

transmission type sensor is also known as intermittent sensor, consisting of a front mounted infrared emitter and detector, a small gap between the two, when a similar cycle of the transmitter and detector object code by Once through the gap between the device will block the beam, the sensors can detect if an object exists. Vishay Surface Mount Transmission (intermittent style) TCPT1300X01 photoelectric sensor and TCUT1300X01, reached the level of the junction temperature of 145, -40 ~ 125 range operating temperature and moisture sensitivity level 1 (MSL1).

The radar technology is the design of innovative driver assistance, to avoid the affects of traffic accidents. Automotive radar systems can send radio frequency electromagnetic waves, these electromagnetic waves encountered the vehicle in front or other objects can be reflected, the radar chip is responsible for sending and receiving of radio signals, and a therapy. Evaluation context to determine the distance between vehicles and other vehicles and other vehicles speed. Therefore, when the forecast to take place when the vehicles collided, head restraints and seat belts will be ready in advance, to help reduce the impact of the accident. At the same time, the same signal is also sent to the brake system or airbag system. Infineon RXN7740 radar is suitable for frequency range 76-77GHz highly integrated front-end chips, including the oscillator function block, suitable for power amplifier and four mixers for multiple antennas. Separate these functions with the current radar system that the radar system will allow manufacturers to reduce the size of a quarter of the radio frequency module for more than 20% reduction in system cost.
