High-Speed Inter-Chip (HSIC) USB 2.0 Hub and Flash Media Controller Datasheet 3.5 Port Power Control 3.5.1 Port Power Control Using a USB Power Switch The USB4640/USB4640i has a single port power control and over-current sense signal for each downstream port. When disabling port power, the driver will actively drive a 0. To avoid unnecessary power dissipation, the internal pull-up resistor will be disabled at that time.
High-Speed Inter-Chip (HSIC) USB 2.0 Hub and Flash Media Controller Datasheet Schmitt trigger input will register this as a low resulting in an over-current detection. The open drain output does not interfere. 5V PRTCTL3 USB Device USB4640/40i 5V PRTCTL2 USB Device Figure 3.3 Port Power Control with a Single Poly Fuse and Multiple Loads When using a single poly fuse to power all devices, note that for the ganged situation, all power control pins must be tied together.
High-Speed Inter-Chip (HSIC) USB 2.0 Hub and Flash Media Controller Datasheet The SPI_SPD_SEL pin is used to choose the speed of the SPI interface. During nRESET assertion, this pin will be tri-stated with the weak pull-down resistor enabled. When nRESET is negated, the value on the pin will be internally latched, and the pin will revert to SPI_DO functionality. The internal pulldown will be disabled. The firmware can determine the speed of operation on the SPI port by checking the SPI_CTL.
