Part Number: TPS65987D

Hi, everyone,

In datasheet of TPS65987D,

it says 2.57V <= Vcx_USB_P_2.7V <= 2.79V.

www.ti.com/.../tps65987d.pdf

How about Vcx_USB_P_2.0V ?

As you know, in 2.7V divider 3 modes,

D+/D- volotage is 2.7V or 2.0V.

Hi Maurice,

Divider 3 is 2.7V on D+ and 2.7V on D-. Divider 1 and Divider 2 are where 2.0V is on one USB data pin and 2.7V is on another USB data pin. We only show 2.7V and 2.7V because this is the highest current advertisement for Divider 3 mode. If any legacy device that detects Divider voltages detects Divider 3, then that legacy device can pull its maximum current.

If this answers your question, PLEASE select This resolved my issue

Thank you,
Eric
