TPS65911: TPS659113 EOLA and finding for recommended replacement

We want to use TPS6591133 as the replacement on TPS659113 EOL and we would like to clarify some of our doubts...

For current TPS659113, we used EEPROM default setting on power supplies and timing, when we migrate to TPS6591133, will the EEPROM default setting on power supplies and timing will be same as TPS659113 as long as we swap the GPIO0 and GPIO7 ?

Thanks in advance,

Hi, Mr. Lim,

Yes; replacing TPS659113 by TPS6591133 is just a swapping of GPIO0 and GPIO7 connection.

Hi Phil,

Thanks again for the clarification.

I ask this again is due to I measure both units (TPS659113 & TPS6591133) and found the sequent is not follow to the datasheet. I further my analysis and found that there are leakage on one of the rail during power up and since I was using digital channel trigger at 1V, and the leakage more than 1V, so I see the false trigger. The leakage is from my circuity and back flow to the PMIC. I will solve that leakage.

If I ignore the leakage, I see the sequent now. Thank you again for the reply.

One more questions, is that a ways to reprogram the sequent? I didn't see any register for that so I ask.

Thanks,
Best regards,
Alder

Hi, Alder,

There is no way to reprogram the sequence; it's fixed by OTP released.

Thanks Phil and noted about the sequent.

Appreciate a lot on your reply.
