Having some issues with the DRV2667 and trying to narrow down potential causes. I'm thinking the switch inductor is sized to small; the device is rated to 1.8A and the drive current (Rext) resistor is set to 1.8A (8.87k). We are having some failures of the inductor but still debugging to see if this is really the case. On failed units if the inductor is replaced the device functions normally again. We've had less than 5% failure. I've left the In+ and In- inputs floating, by thoughts are these should be tied off to ground or vdd, any suggestions?
