DRV8834: PPAD and GND

Hi all,

At this device's EVM that PPAD and GND connected near.

Another motor driver's PPAD and logic-GND does not connected to near.

Can you recommend PPAD connect to near the GND-pin?

Regards,

ACGUY

    Hi ACGUY,

    The EVMs typically connect the GNDs close to the PPAD. Connecting the PPAD near the GND pin reduces the voltage difference between the PPAD and GND.

    One exception is the DRV8844, which can be used as a dual supply EVM.
