Part Number: DRV8848

I would like to use DRV8848 in order to control DC Lathe Valve Solenoid. Positive pulse open the Valve, Negative pulse close.

(I am using TPS61085 as a step up convertor up from 3.6 to 17V) , Bin1/Bin2/nSleep are controlled by the CPU.)

I don't need any current control. 

Currently The DRV8848 doesn't work, seems like there is a load on the VM pin.

1: Please let me know if you can see any problem with schematic.

2: Do you think that DRV8848 is the solution to my problem.ValueControler _ PAGE1.pdf

  • Hi Avraham,

    Can you share a scope capture of your outputs as you open and close the valve, along with VM when the problem occurs?
