Today to share the knowledge of wireless charging MCU to meet what requirements, which will also explain the wireless charging MCU, if you happen to solve the problem you are now facing, don't forget to pay attention to the site, now start!
< ul>New Apple patent reveals new possibilities for wireless charging in the near future, Apple IncA new patent has aroused wide concern in the industry. Unlike the common NFC technology on the market, Apple's patent seems to aim at the practical application and efficiency improvement of wireless charging technology.
1, MCU (MicroControlUnit) the Chinese name is called a micro control unit, also known as a single chip microcomputer (SingleChipMicrocomputer) or MCU. It refers to the emergence and development of large-scale integrated circuitsThe computer's CPU, RAM, ROM, timer and a variety of I/O interfaces are integrated on a chip to form a chip-level computer, which can control common memory devices in different combinations for different applications.
2. MCU chip, full name of MicrocontrollerUnit, is an integrated circuit chip.
3, MCU chip full name is Microcontroller Unit, Chinese name microcontroller, is a special integrated circuit chip. Unlike conventional chips, MCU chips are integratedMany electronic components, such as CPU, RAM, ROM, I/O interface, etc. It can control external electronic devices and perform internal procedures, and is widely used in various electronic devices, such as furniture appliances, automotive electronics, and so on. MCU chip has two main functions: control and calculation.
4, mcu chip refers to the micro control unit. MCU chip, also known as A single chip microcomputer or single chip microcomputer, is to appropriately reduce the frequency and specifications of the central processor, and the memory, counter, USB, A/D conversion, UART, PLC, DMA and other peripheral interfaces, and even LCD driversThe circuits are integrated on a single chip to form a chip-level computer, which does different combination control for different applications, so the MCU chip is a single-chip chip.
5, MCU is the abbreviation of Microcontroller Unit, it is an integrated processor, memory, input and output interface and clock components of the chip, can achieve a variety of control and computing tasks. MCU is usually used in embedded systems, such as smart home, smart wearable devices, industrial control and other fields, because it has the advantages of small size, low power consumption, and low cost.
6, mcu chip technical principle: MCU and temperature sensor through the I2C bus connection. The I2C bus occupies two MCU input and output lines, and the communication between them is completely completed by software. The address of the temperature sensor can be set by 2 address pins, which allows 8 such sensors to be connected simultaneously on an I2C bus. The 7-bit address of the sensor has been set to 1001000.
Such as rightFor 6-10 layer memory module PCB design, it is better to choose 10/20mil (drill/pad) pass hole, and for some high-density small-size boards, you can also try to use 8/18Mil pass hole. Under the current technical conditions, it is difficult to use a smaller size of the hole (when the hole depth exceeds 6 times the diameter of the hole, it is impossible to ensure that the hole wall can be uniformly plated with copper); For the power supply or ground wire hole, you can consider using a larger size to reduce the impedance.
Control chip: manages the entire wireless charging process, including voltage regulation, power control, communication and other functions. Power amplifierLarge apparatus (PA) : Increases signal strength in order to transmit energy efficiently. Oscillators and modulators: Generate high-frequency AC signals for wireless transmission. Coils: Used to generate or receive electromagnetic fields, are a key part of wireless charging.
In the range of ravg 0~0.08 m, the output power increases first and then decreases with the increase of coil turns; In the range of ravg 0.08~ 0.4m, the output power decreases first and then increases and then decreases with the increase of coil turns. For a fixed operating frequency, the quality factor Q mainly depends on the shape and size of the coil and the size of the coilThe materials used. Standard coil technologies (such as wire winding coils and PCB coils) generally specify quality factor values.
Wireless charging PCB, different functions, the required components are different. The required components are: resistor, capacitor, resonant capacitor, resonant coil, MOS tube, control chip, protocol chip.
1. Take out the iphone8 that needs to be charged. iphone8 wireless charger need to buy their own, officially boughtMobile phones do not send wireless chargers, take out the wireless charger purchased. Wireless charger is the need for external power, plug the charging head into the socket. Hold the iPhone8 in range of the wireless charger with the screen up and the back down. You can see that the phone starts to charge, and wait for the charging to complete.
2, this car can be purchased wireless charger implementation, do not need to download software. According to the inquiry car home official website shows that Qijun does not have built-in wireless charging function, you can buy a wireless charger, connect it to the car charger location, you can use wireless charging function. Suitable for strange JunThe wireless charger of the model has Tracy, Dream Duofu and so on.
3, the second step, we click wireless reverse charging. The third step, put the device that supports wireless charging on the back of the machine, you can wireless charging. The basic principle of wireless charging: electromagnetic induction of a certain frequency of alternating current in the primary coil generates a certain current in the secondary coil through electromagnetic induction, thereby transferring energy from the transmission end to the receiving end. At present, the most common charging solution uses electromagnetic induction.
4. No. Wireless charging is already built into the phone itself and can be used without installing any software. There is noLine charging is a charging method based on the principle of electromagnetic induction, as long as the mobile phone that supports wireless charging is placed on the wireless charger, it can be automatically charged without using a charging cable connection.
5. What does GURU do? According to the current conclusion on the Internet, this GURU is essentially a startup company specializing in wireless charging solutions, and has just completed $15 million in financing, and there is no specific product launch.
6, Qi: is one of the most common, some big manufacturers are involved. It seems convenient, but wireless charging has obvious disadvantages
