    Michael, I would recommend reading the Quick-start Guide appnote: SLUA421A. You may find it in here: http://focus.ti.com/docs/prod/folders/print/bq20z90-v150.html A direct link to the file is here: http://focus.ti.com/general/docs/litabsmultiplefilelist.tsp?literatureNumber=slua421a Description...

  • Forum Post: Re: Whoa! - Look what needs a reset.

    SW5307
    Michael, This brings up an interesting topic - How AFE (such as bq29330) registers work. At device reset (either a POR, or a software full reset through MAC command 0x0041), the GG (such as z90) writes to the AFE registers with what it wants. The configuration for the SC thresholds and dwell time...

  • Forum Post: Unable to do complete RESET on BQ27501

    Roger Yttervik
    Hi I have come across a strange issue regarding RESET on the BQ27501. I am using the EVSW connected to pcb which we have designed, containing a bq27501. I have 2 battery packs with completely diiferent chemisteries. They do NOT however have RID sense resistors. I must therefore simulate these...

  • Forum Post: Question about maximum input ratings on BQ20Z95 SAFE, MRSTn and PRESn pins...

    Neil Ragsdale
    The datasheet for the BQ20Z95 says the SAFE, PRESn and MRSTn pins can't go more than 0.3V above the REG25 pin levels. A few comments and questions: 1) The BQ20Z95 reference design has the OUT (pin 1) from a BQ29412DCT fed to a voltage divider and then a diode to the SAFE pin on the BQ20Z95...

  • Forum Post: Impossible to erase the flag HSC or HOCD of bq78pl116

    Julien GELAY
    Hi, I work recently on bq78pl116, to update our BMS running for about a year on bq78pl114. Bq detects when the HSC or HOCD, he do not want to clear the flag . When there is no detection, the circuit works properly ! We see the recovery , but the flag does not turn off and therefore the MOSFETs...

    abraham gonzalez
    I'm using a bq2014H and I'd like to know whats the procedure to send a "charging is DONE" command to trough the HDQ communication. The datasheet describes the procedure to make a reset via software by writing zeros to some registers. I know there's a DONE pin which on high...

  • Forum Post: bq2014H send soft DONE trough HDQ

    abraham gonzalez
    Hi, I'm using a bq2014H (I can't change it to bq2060) and as far as I know, on battery change event the user MUST fully charge and then fully discharge so the device can "learn" the new capacity of the batteries. I also know there's a DONE pin which on high state automatically...
