On my TUSB4041 EVAL board, PwrCtl1/BatEn1 is always 3.3V, whether an upstream device is plugged in or not.
On the board that I designed with this chip, PwrCtl1/BatEn1 is always 0V, and my accessory is not working. I'm using the PwrCtl1/BatEn1 to enable a TPS2051CDBVR (active high) current limiter for VBUS.
I'm using a cellphone as the upstream device, and a joystick as the downstream device on Port 1.
I checked the following pins on my board after power up:
test trstz 0v
smbusz 3.3v
scl_smbclk 0v
sda_smbdat 0v
pwron1_baten1 0v
autoenz 3.3v
ganged_hs_up 0v
pwrctl_pol_tdo 3.3v
fullpwrmgmtz 0v
They all match the Eval board except the PwrOn1_BatEn1.
Any suggestions on how to make Power Control pin high?
Thanks.
