Hi Team,

My customer considers to use DRV2603.

In his application, LRA(Samsung) is connected to DRV2603 through AWG30 cable, the length of that is about 30cm.

Does DRV2603 normally track the resonant frequency of an LRA through this long cable?

(Is it possible case that DRV2603 couldn't monitor the back-EMF normally due to cable impedance?)

Best Regards,

Yaita-san,

The length of the cable should not be an issue. We typically test with wires that are longer in our lab, >50cm.

To test if performance is okay, please compare the waveforms in the DRV2603EVM-CT User's Guide with waveforms taken on the customers device.

Let me know if you have any questions.

Thanks,
Brian
