DRV10983EVM: DRV10983EVM problem

Part Number: DRV10983EVM

Hi team

Good day

My customer need some help:

Is ok to run before , but recently DRV10983EVM and USBANY communication error



  • Hi Aosker,

    Thanks for posting on the MD forum.

    It seems like you're having trouble communicating with the logic core. To further assist you, can you tell me some of the following voltages?

    VCC (Device power supply, max 30V)

    V1P8 - Make sure this is 1.8V, because this is the supply to the logic core. I also want to note this is an output, but not specified to drive external loads.

    V3P3 - This 3.3V LDO is powered by VREG, and the 3.3V LDO powers the 1.8V LDO. 

    Also, both V1P8 and V3P3 capacitor must be connected to GND.

    After you check these I can further help you debug.
