Part Number: TPS65185

Hi TI expert

We now use TPS651851RSLR for E Ink Electronic Paper Display application.

Main Soc Qualcomm, run Linux system.

Then, we need the original Code to set TPS651851RSLR via I2C.

Could you help to provide it? Thanks.

    Hi,

    Unfortunately TI does not have dedicated Linux drivers to use with this PMIC. As you mentioned it is entirely configurable through I2C commands. The general procedure is

    1. Connect the battery.
    2. Set WAKEUP = high with PWRUP = low to enter STANDBY mode.
    3. SoC configures the PMIC registers with a series of I2C write commands (see the datasheet for a full list of writeable registers). 
    4. Set PWRUP = high to start the PMIC power up sequence.

    The exact register settings are for the customer to decide what is best in their application. 

    Thanks,

    Gerard
