DRV8714-Q1: Additional Protection at gate pin

reshma b

Part Number: DRV8714-Q1

Tool/software:

Hi,

I am working with DRV8714 and DRV8706 for my motor control application. Do I need to add gate source protection clamping diode external to the driver IC from GH to SH and GL to PGND. From the block diagram this is already included inside for the high side MoSFETS but not provided for the low side MoSFETs for DRV8714.Do I need to add this protection externally for any of these MosFETs. Please confirm if it is required for driver 8706 also.

Thanks and Regards

Hi Reshma,

No external components for clamping are needed for the DRV8714 and the DRV8706.

Can you tell me where this need is coming from?

Best,

Hi Keerthi,

This is just a query from my end. To understand if any protections is required for external Mosfets. For conventional gate drivers we use to provide this clamping diode for protection.

Hi Reshma,

If there are no further queries, then I will close this thread.
