USB-PD-CHG-EVM-01: How to Tell Current?

Part Number: USB-PD-CHG-EVM-01
Other Parts Discussed in Thread: TPS25750, BQ25792


Is it possible for an MCU to request the USB charge/discharge current (preferably battery side, but I'll take either) over I2C? For example, could the MCU send messages to either:

  1. The TPS25750, or
  2. The BQ25792 (using the "I2Cr" command to get the TPS25750 to relay the request)

Alternatively, I suppose a status of something like "charging", "discharging", or "idle" might be sufficient for my application (but current would be easier to work with from a controls perspective).
