Rohm公司的BD57121MUF-M是汽車NFC兼容無(wú)線功率發(fā)送器評(píng)估板,包括了ROHM公司的汽車級(jí)(AEC-Q100規(guī)范)無(wú)線功率發(fā)送控制IC(BD57121MUF-M)和ST公司的NFC閱讀器IC(ST25R3914)以及8位MCU(STM8A系列),兼容WPC的Qi標(biāo)準(zhǔn),充電高達(dá)15W,多線圈設(shè)計(jì)加寬了充電范圍(比單線圈大2.7倍),輸入電壓11.0-13.0V,輸出電壓12.0V(接收邊),輸出電流1.25A(接收邊).本文介紹了評(píng)估板BD57121MUF-M主要特性和性能指標(biāo),無(wú)線功率傳輸和NFC的系統(tǒng)配置圖以及評(píng)估板BD57121MUF-M主要元件,框圖,連接圖,電路圖,材料清單和PCB設(shè)計(jì)圖.

ROHM has recently announced the development of an automotive wireless charging soluTIon with integrated NFC communicaTIon. This soluTIon combines ROHM’s automoTIve-grade (AEC-Q100 qualified) wireless power transmission control IC (BD57121MUF-M) with STMicroelectronics’NFC Reader IC (ST25R3914) and 8-bit microcontroller (STM8A series). In addition to being compliant to WPC’s Qi standard supporting EPP (Extend Power Profile) that enables the charger to supply up to 15W of power, the multi-coil design enables a wide charging area that provides some spatial freedom in vehicle applications (2.7x greater charging range vs single coil configurations). This means that consumers do not need to worry much about exactly aligning their smartphones to the provided charging area in order to be able to charge wirelessly.

Wireless charging technology, commonly used in portable devices such as smartphones to improve the safety and resistance to water and dust of connectors, is seeing increased adoption in infrastructure applications including vehicles, hotels, airports, cafes, and similar public locations. At present, Qi, the most popular standard, has already been adopted by the European Automotive Standards Group (CE4A) as the charging standard in vehicles, and by 2025 it is predicted that most cars will be equipped with Qi-based wireless chargers.

Meanwhile, NFC communication provides user authentication to allow Bluetooth/WiFi communication with infotainment system, lock/unlock the doors, and allow engine start. NFC also enables vehicle setting customization for multiple drivers such as seat and mirror positioning, infotainment pre-sets, and navigation destination pre-sets.

BD57121MUF-EVK-001 Evaluation Board is based on the BD57121MUF-M Automotive-grade wireless power transmitter IC. This boardintegrates the ST25R3914 NFC reader/writer IC from ST Microelectronics to detect the presence of any NFC cards or tags and to preventdamaging of the NFC antennae by the wireless power transfer system. Wireless power transfer is compliant with WPC Qi ver1.2.4 and can supplypower up to 15 W (output in receiver). Detection and identification of NFC Type A, B, F and V are possible.

評(píng)估板BD57121MUF-M主要特性:

?Compliance to WPC Qi ver1.2.4
?Support of Multiple coils to increase charging area(Qi MP-A13 coil type)
?Power control using fixed frequency and variable voltage
?NFC card/tag detection of Type A, B, F, V
?Housing size: 120 mm x 65 mm x 30 mm

These are only representative values, and they do not represent guaranteed values of the product characteristics.
VIN = 12 V, unless otherwise specified.


System configuration for wireless power transfer and NFC

Wireless power transfer system consists of a two-way power transmission and communication system using a transmitter and areceiver, and the NFC system also communicates between the reader (= transmitter) and the listener. A single Microcontroller (MCU)controls both wireless power transmission and NFC reader, so it is possible to have seamless operation between each other.
