Other Parts Discussed in Thread: BQ24600
Tool/software:
In my application I am using the TPS25730 to negotiate the highest Voltage and Current PDO contract available from the PD Power Adapter.
Then I extract the established PDO contract via I2C and use the Voltage and Current rating and command two BQ24600 Battery Chargers to match the input Power.
This way I can charge the battery packs of my device at the highest available Power.
The problem I have is if the user plugs my device into a Non-PD adapter that only has USB-C 5V / 0.5A, 1.5A, or 3.0A modes.
The TPS25730 had the ability to detect these three USB-C current modes (Figure 8-15 of the datasheet), but I can not find any way to retrieve this detection result.
Is the information available somewhere in the I2C Registers?
I can not find it anywhere in the documentation, it's possible i'm missing it.
I'm not sure the purpose of detecting the Rp modes if the result is not used, so I thought I would ask about it.
I may have to add an extra circuit to detect the voltage again but that comes with extra cost and complexity.
