MIC2829 3G-4G USB Wireless Application Power Technology Design

Abstract: This paper introduces the design of a communication module of USB bus and CAN bus based on DSP CAN controller and USB chip, and proposes a scheme to connect CAN bus network with computer by using USB interface. By using USB100 chip, the computer RS ​​232 serial port can be upgraded to USB interface without

　　1. Introduction 　　Using DSP ( digital signal processor ) as the controller and connecting it to the host computer via USB (universal serial bus) will be a possible development trend of the data acquisition and processing system. 　　1.1 Digital Signal Processor DSP 　　DSP chip, also known as digital signal process

As the functions of smart handheld devices such as mobile phones and tablets in people's hands are constantly upgraded and powerful, entertainment and personalized applications have also made the battery life of devices a dead end. In real life, we may often see friends around us carrying a mobile power bank . Wit

Summary: This circuit utilizes all the power from the USB port by dynamically adjusting the amount of current delivered to the load, thereby siphoning power from the USB port to obtain a relatively stable (and maximum) current from the USB port. It includes a current-sense amplifier (MAX4173), a voltage reference (MAX6

    With the widespread use of portable devices, mobile storage devices are widely used for information storage and transmission. Among the many storage devices currently available, USB flash drives have been rapidly popularized due to their small size, large capacity, easy to carry, and hot-swap support. Moreover, wit

　　Features 　　Switching regulator makes full use of limited power drawn from USB port to charge battery and power application 　　180mΩ Internal Ideal Diode and Optional External Ideal Diode Controller Seamlessly Provide Low-Loss Power Path (PowerPathTM) When Input Power is Limited or Unavailable 　　Full-featured Li-ion

The H.264/AVC standard has a series of new features that are superior to MPEG4 and H.263. Under the same reconstructed image quality, H.264 saves about 50% of the bit rate compared to H.263. However, the cost of saving the bit rate is to increase the complexity of the algorithm. Since it is no longer possible to ach

Universal Serial Bus It is an external bus structure used to connect USB-compatible peripheral devices to the host. It is mainly used for medium-speed and low-speed peripherals. USB is connected to the internal system data line of the PCI bus to achieve data transmission. USB is also a communic
