BQ25A Datasheet Battery SMBus Charge Controller TI

Hey, So after months years! Currents are positive into, negative out of the specified terminal. It seems to have stayed the same except that. This is the best i have found so far is this. No, create an account now.

No luck with that replacement battery unfortunately. More annoyingly, the machine would randomly power off when the battery ran out of juice - even when plugged in.

Interesting behavior you described here. The bqA charges one, two, three or four series. Nine clock cycles are required to transfer each byte in or out of the bqA because either the master or the slave acknowledges the receipt of the correct byte during the ninth clock cycle. In case that one of you has bought one of thouse replacements, and is disapointed, i'd like to take a look at that bettery! That bugger regulates the chraging- voltage that is supplyed to the battery.

Do you already have an account? During battery charging, as the system power increases, the charging current will reduce to maintain total input current below adapter rating. Requested a replacement from the vendor, hopefully the next one works better. Interested to hear if anyone has any experience with these brands!

Consult Packaging Section of the data book for thermal limitations and considerations of packages. Selector and Advanced Circuit Protection.

Maybe that is worth a look. Typically the battery depletion threshold should be greater than the minimum system voltage so that the battery capacity can be fully utilized for maximum battery life. Use Ri and Ci for adapter hot plug in voltage spike damping.

Enhanced pulse width modulator epwm module pages. Higher switching frequency allows the use of smaller inductor and capacitor values.

Feels like I have a new laptop again, and finally able to use it for a few hours without being plugged in all the time! The adapter detect threshold should typically be programmed to a value greater than the maximum battery voltage, introduction to phonology pdf but lower than the maximum allowed adapter voltage. The via size and number should be enough for a given current path.

Hi, Has anyone tried any of the replacement batteries available on Amazon? Note that adding filtering also adds additional response delay. As the system current rises, the available charge current drops linearly to zero. Every shop i found that carrys these interestingly has the same pictures and that looks a bit scammy.

When the input current exceeds the set input current limit, the bqA decreases the charge current to provide priority to system load current. Maybe the Datasheets on those can tell interesting storys.
