Tool/software:
Hello,
We are planning to use TPS62875 and TPS65224 in the design which needs to start at specific voltage settings.
The datasheet says that the default settings are taken from non-volatile memory, so I am assuming that it has to be programmed.
Is there a detailed description of the programming algorithm that we can implement? Is there a specific tool/spreadsheet to generate programming information?
If we build such programmer, what is the interface to the PMIC to program non-volatile memory - I2C? Any additional signals or voltages involved in programming?
What is the state of the device when it comes from the factory?
Hi,
I don't support the TPS65224, so you would need to submit a new post to have that group respond.
For the TPS62875-Q1, the devices comes pre-programmed to these values in the D/S:
The same device comes in a non-Q1 version, TPS6287B20, which allows setting any startup voltage.
Does that help?
Thanks,
Chris
