Other Parts Discussed in Thread: DRV2603, DRV8601, DRV2605L-Q1

Hi,

I would like to confirm the specification to drive LRA.

There is a specification on the datasheet as below. (Load Impedance, 8ohm @5.2V)

Does this mean that DRV2603 can drive 5.2V/0.65A(=5.2V/8ohm)?

Thank you in advance.

Hi, Takumi-san:

Yes.

Way I know what's your application?

Hi Peter-san,

Thank you for your reply!

I understood.

The question is from my customer and the detail is unknown probably automotive.

Best Regards,

Peter-san,

Sorry, can I ask you one more question?

The customer is also considering to evaluate DRV8601.

The drive specification of DRV8601 is 3.3V/0.4A(Max).

On the other hand, the specification of DRV2603/2604L/2605L is 5.2V/8ohm.

Does this mean, the drive capability of DRV2603 is bigger than DRV8601, correct?

Hi, Takumi-san:

if the customer's application is automotive, we only have DRV2605L-Q1 version for automotive.

DRV8601 VDD max is 5.5V, and the minimum load is 6.4Ohm.
