Automobile tire intelligent monitoring system (TPMS) and automobile airbags and anti-lock braking system (ABS) have been widely recognized and popularized as the three major safety systems for automobiles. TPMS related products and technologies have ushered in the development opportunity period in recent years. . In particular, with the implementation of relevant global regulations - for example, in 2007 the United States forced all vehicles to be equipped with TPMS, the EU also requires the use of TPMS from 2014, and countries around the world have joined the ranks of mandatory TPMS.
On the October 20th, the automotive electronics industry has two important product launches that deserve special attention - Freescale announced the launch of FXTH87, the world's smallest integrated tire pressure monitoring system, and Shanghai Baolong Automotive Technology Co., Ltd. announced its global launch. The smallest, highly integrated TPMS module. The latter is based on Freescale's successful application of the world's smallest integrated tire pressure monitoring system semiconductor solution.
The world's smallest Baolong D-type TPMS module
As a market leader in multiple automotive components, Baolong Technology's extensive product portfolio has been sold to more than 80 countries and regions around the world. Its new D-type TPMS module uses Freescale, the market leader in automotive electronics solutions. The new tire pressure monitoring system FXTH87, which has set new standards in terms of power consumption, size and weight, will help Baolong Technology to promote its leading product technology globally.
“The demand for tire pressure monitoring system modules is growing rapidly as more and more countries want to take advantage of these solutions that are superior in terms of safety and environment. Our latest platform D-type module is based on Freescale technology. The four-generation TPMS module solution features small size and long battery life. This product is ideal for customers considering the limitations of system space and power,†said Zhang Zuqiu, CEO of Baolong Group.
The smaller TPMS allows module designers to produce smaller and lighter modules that enable more advanced features, such as integrated Bluetooth for the aftermarket, reducing the tire shop's tire balance. Freescale solutions reduce time-to-market, reduce design costs, and provide easy-to-use and acceptable cost while meeting the highest automotive product quality standards.
Baolong's D-type TPMS module uses Freescale's miniature tire pressure monitoring system, which represents the highest automotive quality standards, while also speeding time-to-market, greatly simplifying design, reducing costs and improving ease of use. The main features of the Baolong D-type TPMS module are:
Small size to match all rim profiles while meeting OEM and AM requirements
Net weight is only 8 grams, and security is enhanced at high speeds
Automatic positioning function
Low BOM cost and cost advantage
The world's smallest TPMS semiconductor solution behind the smallest module
The ultra-small size of the Baolong Technology D-type TPMS module benefits from the very compact package size and high integration of the FXTH87 series. The series is available in a 7 x 7 x 2.2mm package and is the smallest in the market. It is 0.3 grams. This size is ideal for developers of tire pressure sensor modules because it reduces both product weight and raw material costs.
In addition to the world's smallest TPMS solution chip package size, which is 50% smaller than competing products, the FXTH87 series has the lowest RF power consumption in the industry. With only 7mA ldd, ultra-low power consumption can greatly extend battery life, which is inconvenient to replace the battery. The application of tire pressure monitoring is critical. In addition, its accelerometers are available in single- and dual-axis options for better and more accurate tire positioning and full interoperability with original equipment manufacturers and aftermarket applications.
"Freescale's highly integrated tire pressure monitoring system features ultra-small package size and ultra-low power consumption, as well as a broad library of support tools for the development of related products designed by Baolong Technology to continuously improve vehicle safety and fuel economy. In this regard, very large support is provided," said Babak Taheri, vice president and general manager of Sensor Solutions at Freescale.
Freescale's range of pressures, from 100-450 kPa to 100-900 kPa, supports the TPMS market for automotive and light trucks. These markets are mainly driven by regulations, and new demands are constantly emerging, with significant growth. Freescale is constantly introducing TPMS products to meet these latest requirements, helping customers easily meet the latest regulatory requirements.
“Ensuring the right tire pressure is one of the most important things the driver does for his car, so that the vehicle is safer, more efficient, and fuel efficient. Freescale's TPMS is such a match. The product demanded by the customer not only reduces the volume by optimizing the integration, but also helps us to greatly reduce the cost of raw materials. It is a solution to achieve 'win-win'," said Zhang Zuqiu.

High-performance tire pressure monitoring module will dig deep into the market gold mine
The TPMS market has ushered in a period of rapid growth in major countries and regions around the world. (Source: IHS iSuppli and Freescale data. Market research is based on the sum of all TPMS solutions, including QFN 9 x 9 mm and QFN 7 x 7 mm packages)
As a low-cost technology that can effectively improve driving safety and improve fuel economy, the tire pressure monitoring system is increasingly used by automobile manufacturers and aftermarkets. According to data analysis by market research firm IHS iSuppli, from 2013 to 2017, the global TPMS market is welcoming a double-digit rapid growth of 10.9% annual compound growth, and China will be the main growth area. Similarly, the market analyst Strategy AnalyTIcs is also optimistic about the growth of the market, and it is estimated that by 2020, more than 80% of the global production of light vehicles will be equipped with TPMS. Among them, relevant regulations have played a key role in promoting the growth of the TPMS market. Currently, major countries and regions including the United States, Japan, and the European Union have issued mandatory regulations for the adoption of TPMS. The EU, China, and Taiwan require 2014. The new car was installed with the TPMS module in the year, and Japan, Korea and Russia began installation in 2015.
TPMS regulatory requirements and implementation schedules for each region.
China is currently the world's largest and fastest-growing automobile market, and its automotive technology is becoming more and more advanced. In particular, safety-related auxiliary function technologies have been widely recognized by manufacturers and the market. In the past, due to cost constraints and the performance limitations of TPMS itself (high power consumption, large size, low precision), the application of TPMS system as a standard vehicle configuration is mainly concentrated on imported and joint venture high-end models, but in recent years, TPMS has been put on the market. The system as a standard car brand has increased rapidly, and the TPMS market is welcoming a period of rapid growth. In particular, local brand cars are very active in introducing safety-critical technologies such as TPMS. In the past year or two, TPMS has been widely used in local mid-level cars and even ordinary cars.
Freescale, the world's leading provider of automotive electronics solutions, and Baolong Technology, the market leader in several automotive components worldwide, have launched the world's smallest TPMS semiconductor solutions and modules, which is the key to this important automotive safety application market. The strongest sound of technology update and upgrade is expected to bring a new wave of high-performance TPMS popularity.
