TPS65219: Initial State of the Controller

Part Number: TPS65219

Tool/software:

When I use the TPS65219 for the first time, what are the default setting for the regulator output voltages and the GPIO pins.  I copied a significant section of a AM62x evaluation board but now the board I have won't power up.  I have applied 3.3VDC to Vsys but the TPS65219 does not do anything.  It is laid out to have a GPIO line enable the +3.3VDC to the AM62 device but that never happens.  All the output regulators have 0VDC on them and it doesn't draw any current.  The Reset pin is connected to the AM62x device but since the device doesn't get any power I'm not sure how to proceed.  Thanks.

  • Hi Eric, 

    Could you specify which specific part number of the TPS65219 you are using?
    Ex. TPS6521904RHBR ?

    The AM62x board uses the TPS6521904RHBR, I believe, but just want to confirm what you are using in your design. 

    Best Regards,
