HI,

Are there any H bridge ICs from TI which will support capacitive loads.

Hi Shafeeq,

Thanks for your question.

If you are driving a purely capacitive load using DRV8837 , then the driver will most likely trigger an over-current protection (OCP) fault due to the large inrush current. So it is recommended to drive inductive loads.

May I know what is the end application you are trying to drive. and the current levels which are required?

Thanks,

Ibinu

Hi Ibinu,

Thanks for your reply.

The bridge will be used to drive hydrophone transducers. The current requirement will be less than 0.4A.

Hi Shafeeq,

Thanks for confirming.

You can look at DRV81xxx family of devices, specifically DRV81602-Q1. These devices have a bulb in rush mode which can help in driving capacitive loads.

Please see the details in datasheet
