AFE4420: Set LED current to >100mA

Franz Schellhase

Part Number: AFE4420

Hi Team,

Can you have a look at the following customer request, please?

I need to set higher LED current values, namely above 100 mA. The board is controlled by a Python script.
In the datasheet it says that the LEDs can be driven with double current up to a maximum of 200mA. But I couldn't figure out how to write the higher current values, between 100 mA and 200 mA in the register. Also, with the TI-GUI, the LED current only goes up to a maximum of 100 mA.

My question is, did I understand correctly that the LEDs can be driven with double current up to 200mA? If it is the case, how are these values written in the register or how can I maybe change the setting in the TI-GUI?

Thank you,

Franz
