We are interfacing HSD to drive DC-Motor with STM8-MCU.
We are expecting current sensing output at the Multi-sense pin of HSD.
Selection of Channel is as per datasheet of VND7140AJTR.
But, when Motor is ON, and Channel-0 is selected for CURRENT sense, we have observed 5V on Multi-sense pin of HSD.
We observe voltage of around 2.5V, even if there is NO LOAD connected to the HSD output.
Please see attached waveform.
