Hi, TI

There is any information for I2C_1 Address? (TPS6522312-Q1)

I checked full datasheet for TPS65223-Q1, but cannot figure out that Address.

Hi Kim,

The I2C address for this configuration is 0x48.

the I2C address comes from the OTP and is thus specific for each TPS65223x device so data sheet doesn't have this information. You will find this information in the user's guide for this device which you can find in the secure folder. You can request access here. The user's guide also has all the other information about the OTP configuration so I highly recommend checking that.

regards,

Niko

Hi Kim,

since this device (TPS6522312) supports multiple PDNs we have a document for almost every PDN separately. The title of the files is of form "TPS6522312RAHRQ1 Rev2 PDN-7A". Also please see this document.

regards,

Niko

I can find out I2C address from those document, thanks.

So, as my understood, TPS6522312`s I2C Address is 0x48-0x4C, right?

Hi Kim,

actually it is as follows:

Page 0: 0x48

Page 1: 0x49

Page 2: 0x4A

Page 3: 0x4B

Page 4 (watchdog): 0x12

The watchdog registers always have their separate I2C address which is the I2C2 address. This is true when using either I2C1 or I2C2 bus for watchdog communication.

regards,

Niko
