In other applications, it can be connected to a GPIO pin of a controller, a fixed delay circuit can be applied, or it can be connected as shown in this circuit. In this application, the PIN input is jumpered high so that the upstream pull-up is applied as soon as peripheral power is applied. This function is controlled by the PIN input. The ADuM4160 has an option to delay application of the upstream pull-up under control of the peripheral. JP1 switches the speed – open=low speed(1.5Mbps), close=full speed(12Mbps). This product support full speed equipment,but unsupported pure high speed equipment (USB2.0).The circuit is pretty straightforward but here is some explanation. This product onboard output power supply 1W,when your usb device working power >180mA, can use USB double-headed line plus power supply. USB wireless network card, some USB3.0 USB flash drive (5)Other common USB peripherals such as mouse, keyboard, USB sound card, USB flash drive, printer, digital camera, USB hub (HUB), USB camera.įull speed equipment: USB flash drive, digital camera, card reader, mobile hard disk, U shield, USB hub AVRJTAG、AVRISP、AVRISPMKII、S-Lab、JET51、J-Link、FET430UIF、PICKIT2、XDS100、LPC-Link、ICD2、USB Transfer serial port (FT232、CP2102、PL2303、CH341 chip). In the industrial environment,USB device Frequent crashes,like USB Mouse, keyboard, USB to serial port and other communication devices,USB isolator can reduce the chance of crashes and damage to these devices in industrial environments,sometimes we need extend USB line,USB isolator can Acting as a very good USB repeater, also can isolation upstream and downstream equipment in ground pressure difference. (4) all kinds of industrial control USB device When you at the process of debugging, often can't connect, simulation is abnormal ,can use USB isolator try to improve this situation. Such as all kind of USB interface JTAG/SWD Emulator、ISP/ASP/IAP/ICP Downloader etc. Part electric circuit contain strong electricity and strong interference( such as high voltage, frequency converter, motor drive etc.) environment,When it related to connecting a computer occasion,must isolate to ensure computer and personal safety.Ĭomputer is a large noise source, in the field of noise sensitivity that we can through this device to USB interface make communication isolate, such as high-precision USB data acquisition system, HIFI sound system. (1) Contain strong electricity and strong interference work environment Let most seller have to produce computer host interface protection part more and more simple, usb interface not only often touch with external,but also supply power to external devices.these situations make many computer usb interface meet problem, Even make the motherboard was damage. USB interface are One of the most commonly used interfaces in electronic engineer and practitioner daily life ,along with computer industry competition increased, product sale price more and more lower. Lc usb isolation module adopt ADI company proprietary iCoupler® technology, It is the industry first single-package USB isolation solution ,Compatible with USB2.0,provides fully isolated 12 Mbps data rates ,isolation 2500V voltage ,Not connect external power supply required, no drive required. USB signals timing, amplitude, direction, rate, and protocol are complicated, so achieved the magnetic isolation of the USB signal is very complicated technology, and this one basically represents the highest levelĤ.Support USB full speed 12Mbps,not support pure high speed equipment.ĥ.Support USB control transfer, bulk transfer, interrupt transfer, sync/isochronous transfer.Ħ.Power supply:take from the computer host USB port USB Isolator USB to USB Isolation module digital signal audio power isolator free drive coupling protection board ADUM3160 ![]()
