DRV8245-Q1: the different between PDRV8245HRXZQ1 and PDRV8245SPWPQ1

Part Number: DRV8245-Q1

Hi, support team

My customer has the questions as follow:

Could you tell me the different between PDRV8245HRXZQ1 and PDRV8245SPWPQ1?
Are the differences only package and pin numbers?
Do they have the same function?

There's a text in DRV8245-Q1's datasheet:
"The devices are available in two interface variants - hardware (HW) and SPI.
SPI interface device has two variant choices, "P" for externally supplied logic supply, and "S" for internally generated logic supply. The SPI variant offers more flexibility in device configuration and fault observability."
What's this meaning?

Thanks so much.

Best regards,
Yuki

Hello, Yuki,

Following the "8425", the "H" means hardware interface; the "S" means the SPI interface. "RXZ" or "PWP" is for the device package/footprint.

According to the datasheet table 5-2, SPI variants are more flexible.

"externally supplied logic supply" or "internally generated logic supply" points out VDD source, externally or internally.

Regards,
Wang Li

Thanks for your helpful response.

Can I suggest that you add a nomanclture section to the datasheet, it is super unclear as it stands.
