TUSB8044: BBEN/GANGED/HS_UP (pin 42) specification

Part Number: TUSB8044

Hi,

I use TUSB8044 in I2C mode. I'd like to use pin 42 as BBEN.

When pull-up the pin 42 with 10K, the voltage become 1.8V.

Does the pin42 have internal 12K pull-down?

Would you tell me the internal equivalent circuit of pin 42?
