Other Parts Discussed in Thread: TPS25820, TPS25810
Hi,
I am using the TPS65981 to charge a Samsung S3 tablet whilst the tablet (as a DFP) establishes a USB2.0 connection with an FTDI FQ232R device (as an UFP).
I am trying to define the Transmit Source Capabilites in the TPS6598X customisation tool so that the maximum current is less than 0.5A. However, I'm finding that reducing the maximum current, say to 250mA, doesn't change the charging current for the tablet. I don't have a PD analyser to check what the power negotiation steps are. Should it be possible to define the maximum current to be less than 0.5A?
