Description:
...The TUSB2040A supports bus-power and self-power modes. The power switching to the downstream ports caneither be controlled individually or ganged using external devices to switch power and to detect overcurrentconditions. Outputs from the external power devices provide overcurrent inputs to the TUSB2040A OVRCURpins and in the case of an overcurrent condition, the corresponding PWRON pins will be disabled by the... ...forming a single-wire bus. After system power-on reset, the TUSB2040A performs a one-time access readoperation from the EEPROM if the EXTMEM pin is pulled high and the chip select of the EEPROM is connectedto the system power-on reset. Initially, the SDA pin will be driven by the TUSB2040A to send a start bit (1) whichis followed by the read instruction (10) and the starting-word address (00000). Once the read instruction is... ...and Low-Speed OperationsC0068 Supports Suspend and Resume OperationsC0068 Pin-to-Pin Compatible with the TUSB2040Device when EXTMEM Pin is Low...
