  • BQ25898: How to set the TS pin's potential to simulate a good temperature ?

    TI Thinks Resolved
    Part Number: BQ25898 Other Parts Discussed in Thread: BQ25798 Tool/software: Hi, We're using BQ25798 IC but facing some issues. We always get "not charging" status, even on default mode (without programming our own configuration to the chip). By dumping…

  • BQ25898: BQ25898 application question

    TI Thinks Resolved
    Part Number: BQ25898 Hi team， will the BQ25898 register 0x00 go to default value when there is USB plug in?

  • RE: BQ25898: BQ2598 Charging

    Hi Sreejitha, Please see my comments below. The BQ25898 is designed to work with an inductor in the range of 1 uH to 2.2 uH. You will need to select an alternate inductor to the one shown in your schematic. If you plan to disable ILIM pin it is okay…

  • RE: BQ25898: Case where REG0D register returns to default after USB connection

    Resolved
    Hi Nishie-san, Please see my comments below. Yuta Nishie said: Is it correct to understand that the VBUS minimum operation voltage is V(VBUS_OP)=3.9V? Yes 3.9V is VBUS minimum operating voltage for buck converter to function. I also mention VSleep threshold…

  • RE: BQ25898: About CHRG_FAULT register

    Resolved
    Hi Yusuke, Please see my comments below. 1) Yes CHRG_FAULT will return to 00 when VBUS returns to normal, but the customer will need to read REG0C twice in a row to see current status. Section 9.2.9.2 of the BQ25898 datasheet on page 27 explains how REG0C…

  • BQ25898: About PG_STAT register

    Resolved
    Part Number: BQ25898 Hi, Could you tell me about PG_STAT and Charging restart condition. If the VBUS voltage drops and PG_STAT becomes 0 and CHRG_STAT becomes 00 (Not Charging), PG_STAT automatically becomes 1 and charging resumes when the VBUS voltage recovers…
