DRV3946-Q1: Current sense scaling factor from 0 to 200mA

Hi Carlos,

Thanks for your question. 

I have one clarification, are you trying to measure the current during the STANDBY mode or a lower current setting in active mode. Please see details on the standby mode below.

While the device is turned OFF(in the STANDBY mode), the current though the load is expected to be IOLP_PD as shown below(Note that this current flows to the internal current sink and will not be shown in the IPROPI current )

Further, in case of a fault OUTx node is OPEN or shorted to GND, CHx_OFF_DIAG_STAT warning is set, indicating loss of relay control.

Let me know if this clarifies. 

Thanks,

Ibinu

Hello Ibinu, thank you for your prompt response.
I'm actually trying to measure a lower current in active mode, around 50mA, I would like to know what would be the scaling factor and error for such current

Thanks for confirming the use case.

I am discussing the accuracy at lower current levels internally with the team. I will give you an update by 5/8/2024.
