Part Number: DRV2603

I have used DRV2603 part in our design to drive https://www.vybronics.com/coin-vibration-motors/lra/v-g0832013d

What if we configure DRV2603 in LRA mode and connect a ERM motor
What if we configure DRV2603 in ERM mode and connect a linear vibration motor
We have issue of DRV2603 getting faulty with PWM pin operating in GPIO mode (O and 1 )

Hi Bhavesh,

This is a good overview of the haptic solutions and it includes the difference between ERM and LRA drives: https://www.ti.com/lit/ml/sszb151/sszb151.pdf

ERMs use a DC drive while LRAs use AC. You're unlikely to damage either motor as long as your stay within the motor maximum voltage specs but it will not perform as expected.

Can you elaborate on your issue with the PWM pin?

Thank you,
Jeff McPherson
