The most important passive safety equipment in the automotive industry is mainly seat belts, airbags and tire pressure monitoring systems. With the concept of energy saving, environmental protection and safety more Sensor and more popular trend, people on the safety of the car put forward higher requirements, especially more and more attention to the tire pressure monitoring system.
As one of the safety equipment tire pressure monitoring system, the tire can appear in a dangerous sign when the police in a timely manner to remind the driver to take appropriate measures to effectively prevent the occurrence Suction Control Valve of the accident. In Europe and the United States and other countries, tire pressure device has been implemented as a standard. China in recent years there are many people began to install the configuration, after all, this is related to whether the normal safe driving.
Mandatory national standards on the tire pressure monitoring sensor put forward higher requirements, the Chinese Ministry of Industry and Information Technology recently led the review through the 'passenger tire tire pressure monitoring system performance requirements and test methods' (GB26149) mandatory national standard draft (Hereinafter referred to as 'standard'). The mandatory 'standard' once implemented, on the one hand will promote the level of vehicle safety and energy conservation, on the other hand the tire pressure monitoring system components Fuel Rail Pressure Sensor of the relevant technical requirements will be more stringent. Based on this, Infineon introduced a new generation of tire pressure monitoring sensor SP40, the product for the needs of Chinese enterprises, while product performance, energy consumption and reliability were optimized for the Chinese tire pressure monitoring module manufacturers to provide a cost-effective solution.
SP40 based on market demand to create a full range of optimized product performance
Infineon's smaller package (59% reduction in volume), lower power consumption (quiescent current from 550nA to 245nA), greater storage capacity (6K Flash) increased after the previous generation of tire pressure monitoring sensor SP37 achieved great success in the market To 12K Flash), higher measurement accuracy (10-bit ADC to 13-bit ADC) of the new product SP40, in addition, SP40 only need a 26MHz crystal fuel metering valve can support two operating frequencies --- 315MHz and 434MHz, and SP37 Two crystals are required to support these two operating frequencies.
In order to better serve Chinese customers, to meet the needs of Chinese customers, SP40 for the needs of Chinese customers were optimized. Not only in the provision of cost-effective, high-quality products in the service system, but also to provide full Chinese web and document support to help customers faster and better understand the product; in the sales channel, through more Speed Sensor than 10 years of cooperation agents This efficient service channel serves the end customer. Infineon will continue to provide high quality and high performance products to ensure better customer service.
