Hi Team,
My customer is surveying 2 ports USB2.0 HUB and TUSB4020BI-Q1 was proposed. There are few questions from customer.
1. Does divider mode support apple 2.4a? (It seems TUSB4020BI-Q1 only support divider mode 1 and 2, right?)
2. Is there any reference circuit can be shared with customer for designing SCH.
3. If TUSB4020BI-Q1 cannot support apple 2.4a, which devices is recommended?
Thanks a lot.

Hello Vincent,
1. Correct the TUSB4020B only supports modes 1 and 2.
2. Please see the schematic in the EVM giuide, https://www.ti.com/lit/ug/sllu219/sllu219.pdf?ts=1590162401143
3. We do not have a similar hub that supports apple 2.4A, but I would recommend using one of the standalone charging controllers and disabling charging on the hub. If an automotive qualified device is needed, this one may work: 
Regards,
