TPS6594-Q1: TPS6594-Q1 WD calculator

Manisha Narayana Gowda

Part Number: TPS6594-Q1

Hello experts,
I am working on TPS6594-Q1. In my case, it is configured to Q&A mode.
I would like to know LONG WINDOW, WINDOW1, WINDOW2 and WD sequence timing. There is no mention of recommended time margin between MCU and TPS6594 in TRM.
Is there something related to TPS6594 just like DRAFT TPS65381-Q1 wd-clock-tolerance-calculation - For E2E.xlsx.

Thanks in advance

Kind regards

Hello Manisha,

we do not offer an excel spread sheet like in the case for the TPS65381 device, but the information that this spreadsheet provides is located in the datasheet for the TPS6594 with all timing requirements along with example diagrams.

The section is located under section 8.3.11

Hi Nicholas
Thanks for the support.

Section 8.3.11 gives more information about the WD in trigger mode.
I am working on WD in Q&A mode.
Can you please let me know what is the recommended time interval for long window, window 1 and window2.
I would also like to know, what is the recommended time interval between Answer3, answer2 and Answer1 in window 1.

Regards

Hello Manisha,

We do not have any recommendations for the Watchdog Q&A sequence outside of what is outlined in the datasheet.

There isn't a limitation on the answer between the times outside of the clocked sequences on the I2C or SPI interface.

Any other additional questions on the Watchdog?

BR,

Nicholas
