- Chipset ( 4 port USB3.0 HUB)
- USB3.0 chipset : TUSB8040A1
- Re-driver : SN65LVPE502A
- TPS2560DRC
2. Question
a. SSTXP can be routed to SSTXM, or SSRXM can be routed to SSRXP., ('RX+ with RX-' / 'TX+ with TX-')
Then, can it apply to SN65LVPE502A for easy route ?
b. I designed USB3.0 HUB using TUSB8040A1 and Re-driver (SN65LVPE502A) [ Upstream port (TUSB8040A1) ß---Re-driver----à PC ]
SN65LVPE502A has two types (A and B)
Which side is the host side? PC or Upstream port (TUSB8040A1) ?
Which type is good to my circuit ?
OR, Don’t care?
c. I want to use TPS2560DRC for downstream port power conorol..
- EVM User manual says if circuit occurs overcurrent, TPS2560 reports OVERCURxZ..
So when TUSB8040A1RKM receive report from TPS2560, does TUSB8040A1RKM give enable signal to TPS2560
through PWRONxZ_BATENx pin.?
- TPS2560DRC Datasheet says TPS2560DRC works in Low Enable.
But TUSB8040A1RKM Datasheet says :
USB Port 0 Power On Control for Downstream Power/Battery Charging Enable.
The pin is used for control of the downstream power switch;
in addition, the value of the pin is sampled at the de-assertion of reset to determine the value of the battery charger
support for the port as indicated in the Battery Charger Support register: PWRON0z_BATEN0
0 = Battery charging not supported
1 = Battery charging supported
I want to cut off the power, when the circuit occurs overcurrent.
Could you check the attached circuit using TPS2560?
d. I want to design a very simple USB3.0 HUB.
It have to support Battery charging of all downstream port.
Can you check option resistors below schematics?
Thanks!
