Other Parts Discussed in Thread: DRV2700
I have a new DRV2700EVM board.
I was able to successfully operate it with the USB GUI software supplied with a piezo actuator connected.
Then I made the following jumper changes and connected to an external 5V bench supply and signal source:
Remove JP5 and JP6
Move JP10 and JP11 to VIN positions
Move JP7, JP8 and JP9 to pull-up position
Connect a 5V bench supply to J2
Connect a signal generator to J5+ set to 100mV sine wave at 500Hz (ground to board GND)
I did not see any significant output from the DRV2700. I started to investigate and found that there is no 3.3V power (voltage across C2 is about 0.5V).
I have been careful and worked under proper anti-static conditions. The power supply never entered an over-current condition.
I believe the board has failed due to a defect. Can I get a replacement?
