DRV2605L-Q1: RTP mode function check

Hanbing Xiao

Part Number: DRV2605L-Q1

Hi team

Customer is using RTP mode of DRV2605L-Q1. But they find the vibration performance is not that good.

Could you please have a look?

Below is the motor datasheet.

Below is their register configuration.

Below is the output waveform

Could you please have a look and give some suggestion?

Hanbing, does the customer have the EVM to test the register configuration? It seems the customer sets the actuator as the ERM, rather than LRA.

Hi Hailong

#define LRA_FEEDBACK_CONTROL_VALUE (uint8_t)0xB6

I find it has been already defined as LRM

Could you please have a look again?

Hi Isaac

Could you please help assign other AE on this case. It seems that Hailong would be OOO for more than 1 week.
