DRV2605: DRV2605 Setting

Part Number: DRV2605

Dear Sir/Ms.

My customer wants to change to a new ERM vibrator because old ERM vibrator is going to EOL.

They have the following questions.
For example, the DRV2605 Library Selection (Address: 0x03) register needs to be named BANK A, B, C, D, E

If the customer uses a new one, how to classify it?

What are the definitions of overdrive rise time and overdrive brake time?

thanks

Hello,

Thanks for reaching out.

Overdrive rise time is equal to time the driver outputs at higher than set rated voltage in order to ERM up to its proper acceleration quickly. Overdrive brake time is the opposite where it is equal to the time the voltage drives negative to decelerate to a stop quickly

Best Regards,

Carson

Hello,

Any or all of these details can be found in the recommended operating conditions section and electrical characteristics at the beginning of the datasheet. But in general the details described is supported by the device.
