DRV8714-Q1: About Factors, Clock and Watchdog Window

Hello Shoji-san,

1. Yes, the min, max and typ values come from testing multiple devices and forming a distribution. From that distribution, the min, max and typical values are calculated.

2. Can you clarify what you mean with this question?

3. Yes 

4. 

5.

6.

7.

Let me know if they need further clarification.

Best, 

Keerthi

Hi Keerthi,

2. The original customer question is as below:

• What is the clock-based control?
• Can the frequency be varied during each control regardless of the register setting? If so, when?

As BU answer in last year, they mentioned that "Only for SPI clock.  The frequency will be the same regardless changing the register." Is this correct?

Could you confirm if these descriptions are correct?

4. For KP_PDR

5. For STC_ERR

6. For KP_STC

7. For DCC

Best Regards,

Shoji

Hi Shoji-san, 

2. Is there a specific register you are talking about or is this a general question about the dependency of the internal clock on SPI and SCK settings.

The descriptions are fine, but you have to keep in mind the parameters such as gain are just an initial guess and the driver computes converges on the best gain value for the given application.

Best regards,

Keerthi 

Hi Keerthi,

2. This is a general question. They don't specified any register.

Understood. Thank you for your confirmation. I'll keep in mind that.

Best Regards,
