DRV2605LEVM-CT: DRV2605L

Part Number: DRV2605LEVM-CT
Other Parts Discussed in Thread: DRV2605L, , TEST, DRV2605

Hello Sir / Madam

I have some questions regarding using DRV2605L in my design and really appreciate if you can help me.

I want to put DRV2605L in my design but I can not find the LRA or vibrator motor you used in DRV2605LEVM-CT in Mouser or Digikey.

I didn't buy the EVM yet and have plan to buy it for testing its feeling. but I want to buy some extra examples of LRA or Motors to test them with your DRV2605LEVM-CT as well.

1. maybe its not a wise question but what is the voltage value of output pins of the DRV2605 to drive the LRA? I have 3.3V and 5V in my design to power the chip but I wanna know if the output voltage is not effecting capacitive touch keypad.

2. do you have some LRA or motor suggestions? to clarify better I want to use this LRA as replacement of a tactile keypad feeling in a capacitive touch keypad of a remote control. at this point the size of LRA is not very critical, but I want to have same feeling like real button as much as possible.

3. As I want to use only one LRA in the middle of PCB and it should be strong enough to give same feeling for all capacitive buttons, is it a good idea to use SMD LRA in back side of the capacitive buttons, like the one you used in DRV2605LEVM-CT, or its better to use another wired one that can be install in the mechanical structure of the remote control to avoid vibration effect on PCB or capacitive touch buttons? I used capacitive touch buttons and the other circuits in one PCB. I prefer to have LRA in SMD to ease mechanical design but I wanna avoid vibration effect too. 

thank you in advance for your help.

Best regards,
