TPS65381A-Q1: how can we use External watchdog PMIC TPS6594-Q1 as program flow monitoring in TDA4VM

Hi Vishal,

I want to get your question assigned to the correct expert, but two different PMIC devices are mentioned - TPS65381A-Q1 and TPS6594-Q1. Can you please clarify?

Thanks,

Matt

i am sorry for typo error, it's TPS6594-Q1. please assign to expert. 

We have split power grouping for MCU Island safety domain and MAIN domain . 

Hello Vishal,

We do offer PMICs that implement a Power Distribution Network (PDN) for the TDA4VM

Hi Nicholas,

Can i get a required physical connections from PMIC (TPS6594) to TDA4VM so that we have the MCU servicing the Watchdog on the PMIC so that the entire system can be reset.

1. connection for MCU receiving Clock from external Watchdog (TPS6594)
2. connection to RESET  clock  between MCU (TDA4VM) to External Watchdog (TPS6594)
3. Connection / specific PIN from TPS6594 to reset  power TDA4VM 

Hello Vishal,

I'll try to get you that information, but the guides to tell what pins are connected to what, but specifically what pins depends on what part you end up ordering.

Hello Nicholas,

A guides to tell what pins are connected would be really helpful.  

Hi Nicholas ,

i have replied to email & i got this link https://www.ti.com/lit/ug/slvuc99a/slvuc99a.pdf.

I'm keen in understanding the necessary physical connections between the PMIC (TPS6594) and TDA4VM to ensure that the MCU services the Watchdog on the PMIC, & if required enabling the entire system to reset. Specifically, I'd like to know:

1. The connection for the TDA4VM to receive the clock from the external Watchdog (TPS6594).
2. The connection for the RESET clock between the MCU (TDA4VM) and the external Watchdog (TPS6594).
3. The specific PIN or connection from TPS6594 to reset the power of TDA4VM.
