Other Parts Discussed in Thread: DRV8662

Hi,

My customer would like to drive 2 PZTs with one DRV8662 by changing something FET switch, for example.

Please look into the block diagram I attached.

This solution is using FET like CSD19534 as analog switch.

Could you consider if this solution is useable?

If not, would you please tell me another solution to realize?

Thank you for your support.

Hi Tamuki,

Although we really haven't tried that specific implementation, it would be the way we'd do it. Please make sure the applied voltage does not exceed the drain-to-source- voltage rating of the power MOSFET.

Let us know how it goes,
