TPS65910 HOT DIE interrupt

Other Parts Discussed in Thread: TPS65910

Hi!

I am using a design that a MCU controls TPS65910 and communicates with SITARA with SPI.

So, its not the MPU that receives PMIC interrupt information.. 

And im testing HOT_DIE interrupt and got a problem..

When i receive this interrupt, i clear the status register and then turn off the TPS65910..

But 10 seconds later, when i turn it on again, the HOT DIE interrupt activates again! So, i do the same thing, and this second time everything becomes normal.. the PMIC goes on..

And, if i dont clear the interrupt the first time.. everytime i turn on TPS65910 it activates HOT DIE again and keep turning off.. infinite cycle..

So.. whenever i turn it off and then on.. it should reset all registers write? Why is this happening?

Thanks,

Daniel.
