Question How do I detect if a USB host is connected to my device? Answer In a self-powered system, it is generally desirable to be able to detect the presence of VBUS. VBUS indicates when a host device has been connected to or disconnected from the USB peripheral. For EFM8 devices, the...

The VBUS impedance detection can detect the soft short on VBUS and warn the user about the potential connector overheating. The MAX20330 is designed to drive a single or dual back- to-back external N-channel MOSFET with a low RON (10mΩ max). An external TVS can be used to protect the...
Using CyU3PUsbControlVBusDetect(CyBool_t enable, CyBool_t useVbatt): a. VBUS detection can be made to happen using VBATT pin (In this case useVbatt is set to true) b. By making both the above parameters false, VBUS can be connected to a GPIO and necessary handling can be...
I designed a board, based on the LPC2388, with an USB device interface.The VBUS (pin P1.30) is used as an ADC and not as a VBUS detector.QUESTION 1Can I use a GPIO pin to detect the status of the VBUS?QUESTION 2Which software corrections I have to do to Kei...
When plug USB OTG cable, The level on USB_OTG_ID pin will be changed, it is connect it to PC USB, the level should be 2.5V, if it is disconnected ,the level should be Low, so if you select "USB OTG pin detect support" in linux kernel, you should detect OTG cable status. Regar...
