Part Number: TPS549D22 Hi TI,
I can't assert SMB_ALRT pin. The following is my test command.
Test command: # Check write protect. # 0x0: Enable writes to ALL commands i2cget -y 0 0x14 0x10 -> 0x00
# Read VOUT_MARGIN_HIGH i2cget -y 0 0x14 0x25 …

Hi Team,
Customer wants to change the voltage setting in the internal NVM.
It will be difficult for my customer to turn the output off while device is operating to use STORE_DEFAULT_ALL, as they would end up violating their power…

I have a question about the default values of the following registers on reset...
「 VOUT_COMMAND 」 「 VOUT_MARGIN_HIGH 」 「 VOUT_MARGIN_LO 」
The lower 10-bits are set by the pin-strap on boot/initializaiton. I understand that the initial boot…
Part Number: TPS549D22 Hi Team:
Can you help to comment on the following questions, thanks!
1: there is no statement on the PMBUS Pin , such as open drain, if this device is the open-drain type? if the external pull up is need? because there is no any…
Part Number: TPS549D22 Hi Ti Expert:
We have the design as below:
1. Vset=0.75V
2.Rtop=10K, Rbot=63.4K to get Vout=0.87V
Now, we need to adujst the Vout to 0.83V on the flying, what is the step to do it?
Thanks
Part Number: TPS549D22 Dear team
