Other Parts Discussed in Thread: TPS65987D

Dear Ti Sirs,

Regarding with TPS65988 or TPS65987D is it possible to use I2C Master and GPIO based control of external components like crosspoint switch and  other components in the same system at the same time?

I mean part of PD  controller command come out by using I2C Master (for crosspoint switches) and part of the command come out by using GPIO pin (for instance digital output signal).

    Hi Pekka,

    Yes, the TPS65987D/88 both support I2C master and GPIO events. However, the I2C3 pins are multi-use. For those pins, you can only use them as either I2C or GPIO, not both.

    Thanks,
    Eric
