  • Forum Post: Re: TPS65073 Converters Power Up

    ChristianHoefling
    Please have a look at page 34 figure 33 of the TPS65073 datasheet. Figure 33 shows the state diagram of the TPS65073. There is a difference if the device is powered from - AC / USB - BAT 1) In case device is powered from AC/USB As soon as input voltage is applied to AC or USB the device...

    Daniel Acevedo
    In the case where the supply is to power up when 5V is applied to the AC pin, the pin named PB_IN (which has an internal pull-up to AVDD6) should be left open and pin POWER-ON needs to be pulled high. If the TPS65070 is powered from the BAT pin, PB_IN needs to be tied low to start the converters.

  • Forum Post: Re: TPS6507x: How can Battery and Adapter be differentiated from each other?

    Daniel Acevedo
    Do not connect AC, BAT and/or USB together. Pins AC and USB are inputs; AC is for an AC adapter and USB is for power from a USB port. The negative connections of all input supplies must be connected to ground. Pin BAT acts as both an input and and output; input when supplying power and output when...

    Daniel Acevedo
    These are common questions which we have covered in the TPS65072 datasheet. Page 25 describes the Power-Path Management and SYS output. "When TPS6507x is turned off and there is no voltage at AC or USB, the SYS output is disconnected internally from the battery. When TPS6507x is turned on by...

  • Forum Post: TPS65070 current differs on AC versus USB pin

    Mike Looijmans
    We are powering an OMAP-L138 via the TPS65070 (on the Logic PD SOM). There's a Li-Ion battery connected to the BAT, which is monitored by a DS2788 fuel gauge. When I power the system via the USB pin, using a source capable of supplying at least 1500mA, and set the current limit for the USB to...

    Hi, We are currently evaluating the TPS65070 PMIC, using the TPS65070 EVM , And we wonder how could we get 3.3V on VDCDC1 outpout , we wish also to turn on a LED when the battery voltage is weak ( battery almost empty). Any help will be appreciated. I enabled the DCDC1 converter trough the CON_CTRL1...

    Matthew Andrews
    According to the State Machine if Figure 33, if I have both the AC and USB pins each pulled low with 100k resistors and set POWER_ON to '0' from '1', the PMIC should go to the "Power OFF, SYS OFF" state. Unfortunately it is going to the "POWER OFF, SYS ON" state. This...
