ROHM has developed the MI sensor "BM1422AGMV" for detecting geomagnetism in the field of vehicle detection for parking lot vehicle management systems.
"BM1422AGMV" is a product that combines the MI component development technology of partner Aichi Steel Co., Ltd. and the semiconductor production technology and sensor control technology that ROHM is good at. It can detect changes in the geomagnetic field caused by vehicles, etc., and it has extremely high performance advantages compared with general products in terms of noise characteristics, temperature characteristics, hysteresis characteristics, and power consumption (the noise impact is only 1/3, The temperature effect is only 1/6, the hysteresis characteristic is almost 0, the power consumption is only 1/8), and the package is packaged in a small package of only 2 × 2 mm. This achieves the industry's highest precision and ultra-low power consumption. As a geomagnetic sensor, it is very helpful for the development and popularization of parking vehicle management systems.
From September 2017, the evaluation board "BM1422AGMV-EVK-001" equipped with "BM1422AGMV" was launched online on the AMYYA360 and RightIC online platforms. This product can be evaluated only by purchasing online. In addition, various documents such as the Getting Started Guide required to use the evaluation board can be downloaded from the official website.
3V Lithium Fluorocarbon TPMS Button Batteries
3V Lithium Fluorocarbon TPMS Button Batteries use fluorocarbon material as the battery positive electrode. The fluorocarbon material has high thermal and chemical stability. It does not decompose at high temperature ≤600℃, and does not crystallize at low temperature. The battery operating temperature range can reach -40~125℃ ; Its chemical stability ensures the safety of the battery, so that the battery has a higher safety performance when short-circuit, collision, and extrusion, and has the characteristics of explosion-proof and spontaneous combustion. Our company uses self-developed electrolyte to make the battery life more than 10 years.
Our BR series button batteries are conventional high and low temperature resistant button batteries, and the working temperature is -40℃~+85℃
Accepts customized upgraded version of high and low temperature resistant button battery, working temperature is -40℃~ +125℃
Battery application range: It can be used in fields that have strict requirements for high and low temperatures and high energy density. For example, automobile tire pressure gauge (TPMS) battery, industrial control motherboard battery, computer motherboard battery, smart instrument battery, oil field drilling platform emergency equipment power supply, marine life-saving flasher, implantable medical battery, etc.
