TPS25762-Q1: Internal register map

Jaroslav Dohnal

Part Number: TPS25762-Q1

Hi,

can you please share an internal register map and descriptions for the TPS25762-Q1? We want to access these registers over I2C2 from a system MCU and get the diagnostic data, similar to EVM. Is there some programming manual I'm missing? The GUI programming is fine for basic functionality evaluation, but kinda useless for any more complex system design.

Thank you.

    Hi JD,

    We have not published a reference manual at this time.  For diagnostic information such as that found in the GUI telemetry tab, I have included register information below.  Be advised reading or writing any other register is prohibited and may compromise device performance.

    An I2C controller should access I2C target address based on TVSP setting. For a single port device, Port A status registers
    can be accessed via 0x22 or 0x23.
    0x1A STATUS Register
    This register returns port status parameters.
    Bits Name Description
    Bytes 6-12: Telemetry
    55:48 VntcVoltage VNTC voltage ADC reading (0.014 V LSB)
    47:40 VbusCurrent VBUS current ADC reading (23 mA LSB)
    39:32 VbusVoltage VBUS voltage ADC reading (0.098 V LSB)
    31:24 VinVoltage VIN voltage ADC reading (0.08 V LSB)
    23:16 IntDCDCCurrCode Internal DCDC Current code reading (25 mA LSB)
    15:0 IntDCDCVCode Internal DCDC Voltage code reading (10 mV LSB)
    Bytes 1-5: Reserved
    39:0 Reserved Reserved.  Read value from this location not valid.


    The preceding content is intended as information only and not a part of the device specification.

    Refer to datasheet figure 9-38 for I2C formatting.

    Hi Erik,

    thank you. This should be sufficient. I'm sure you have your reasons, but please reconsider publishing reference manuals.

    Regards,
