DRV8662: +/- 200V output with analog input

Steven Metzger51

Part Number: DRV8662
Other Parts Discussed in Thread: DRV2700,

I want to drive a 200nf load at +/- 200V with an input signal that stays below 200 Hz. Is there any way to configure multiple DRV8662 or DRV2700 chips or achieve this output.

Hi Steven,

The only way I could think of achieving this is using two of the DRV2700-HV500 EVMs and tie each HV output to the positive/negative terminals of the piezo. We have not tested this, but if you synchronize the input/output signal, it should be possible. There is not a way to stack the voltage for the DRV8662/DRV2700 device.
