TPS25762-Q1: Getting data from an MCU through I2C2t line

Maxime Fortier

Part Number: TPS25762-Q1

Hello, I'm looking through the datasheet and can't find any description how to read data from an MCU.

Can you provide information on what type of data can be obtained through telemetry and how to get it with the I2C2t line as indicated in the datasheet, which mentions its compatibility with an MCU?

Section 9.3.11 I2C Interface:

"the I2C2 port can provide connection status and telemetry information as well as transfer firmware updates from the HUB or MCU to an EEPROM connected on I2C1."

Hi Maxime,

I will look into this and get back to you shortly.

Thanks,

Hi Maxime,

The telemetry data that can be obtained:

NTC pin voltage ADC reading
VBUS voltage and current ADC readings
VIN voltage ADC reading
DCDC1 Current and Voltage code reading

Our GUI supports a Telemetry View to monitor the data visually. See Section 6 in the TPS257XX-Q1 GUI User's Guide.

The TPS25762 device has a status register that can be used to read telemetry data over the I2C1 or I2C2 bus.

BR,

Seong

Hello,

I understand that the device has a status register. Can I obtain the I2C register map as well?

Additionally, can you please provide the proper steps to transfer firmware updates from an MCU? In my application, the MCU must be able to reprogram the device and access the same information as the GUI from the development kit.
