Part Number: DRV110EVM
I am working on DRV110EVM board, I want to control soleniod through Q2 Mosfet. I have connected soleniod to P1 pin2 and P1 pin4 respectively. Input 110VAC, I have shorted JP5, On Vin i am getting 9V.
My issue is i am not able to probe from CRO. If i short CRO gnd to board ground spark is coming and fuse is blowing off.
I have notified our expert regarding this topic. Please expect a response by 8/2/19.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Aaron Goodson:
Seems to me CRO and AC have different GND.
Did you try to bypass the AC, power it directly with DC?
For debugging my suggestion is to:
1) connect DRV110 power on TP11 , 6V<Vin<12V
2) solenoid DC voltage on P1-1 - separate supply for the solenoid
3) connect the solenoid, JP1, JP2 , set the desired R4/R5/R6 for your application. You can toggle the solenoid with Vin or with the Enable pin
With AC supply Vin should be ~15V ( DRV110 internal diode). What is P1_1 voltage? the DC supply series resistance( JP4 and JP5) is to high for the DC voltage after the rectifier.Select Vin series resistance based on Table4 DRV110 data sheet
In reply to Costin Cazana:
1 .Output of bridge rectifier GND and U1 IC GND is common.
2 .For soleniod we are giving 110V DC.
If i use two power supplies, then both the gnd need to be shorted. Can i do it ?

Yes of course, the gnd should be the same
