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