Part Number:DRV110
Hello TI DRV110 Support,
I have ordered the DRV110 Evaluation Board plus 10 ICs of the 8pin Version of the DRV110. I wanted to test the DRV110 8pin IC, but I can't establish a proper Input voltage unfortunatelly.
When I measure directly with a multimeter in Diode-measurement-mode from Pin Vin to Pin Gnd, I measure round about 0.5V. And thats also the voltage when I connect an external voltage supply with (let's say) 15-20V to pin Vin. I also set a current limiting resistor inbetween, so that's not the problem.
I don't have these problems on the DRV110 Eval board. So I also tried to connect the voltage (V_limit) from the Eval Board to the Vin Pin of the 8pin DRV110. I failed too.
I'm really confused but there must be a possibility with that. Thanks in advance!
Cheers
Thomas
