Part Number: TUSB8041

We have following queries regarding TUSB8041

1)Can TUSB8041 support I2C protocol when addressed by a Host instead of SMBus protocol.

2)For power control per port PWRCTL [1:4] which register can be used for configuring the polarity.

Hi Rajashri,

1. In most cases, yes this is possible. Check this app note which describes the differences between I2C and SMBUS: http://www.ti.com/lit/an/sloa132/sloa132.pdf

2. Bit 5 in Reg 0Ah controls power control polarity or it can be controlled by the PWRCTL_POL pin if using pin configured mode.
