Other Parts Discussed in Thread: TPS25910
The Type-C power supply solution is shown in the attachment. The Type-C interface is the uplink data transmission and power supply interface of the USB3.1 GEN2 HUB. The entire HUB solution requires a power supply of 5V 3A. Use TUSB321 as UFP to configure the CC1 and CC2 pins. And a load switch TPS25910 is used to control the 5V VBUS power to prevent its current from breaking the limit. How will I_MODE PIN handle when the TUSB321 is in UFP mode? The data sheet only mentions the configuration in DFP and DRP mode as shown in the attached chart. Since the HUB is in USB3.1 GEN2 mode, do you use a TUSB321 DIR_PIN to control a MUX to distinguish the polarity after access, and DIR should How to design, read a lot of solutions, use 10k resistor to pull up 3.3V, but in my design, because the 5V_VBUS of the type-c interface needs to pass the load switch and then DC TO DC to generate 3V3, and this solution need not be emark Chip power supply, how to handle FLT # _pin, there is no MCU and other processors in this solution.
