Part Number: BQ24140 Other Parts Discussed in Thread: BQ24153A , BQ24156A , BQ25606 , BQ24157 Hi
About bq24140, the range of weak battery voltage threshold (VLOWV) is 3.4V–3.7V, if the battery voltage lower than 2.9V, whether the chip go to precharge…
Other Parts Discussed in Thread: BQ24140 , BQ25606 , BQ24250 Iv'e been reading the datasheet of BQ24140 ( http://www.ti.com/lit/ds/symlink/bq24140.pdf , and there are a few issues which are not entirely clear to me:
1. What happens if both VBUS and…
Hello Kris,
The answer is yes. We have tested the device charging from VIN and boosting at the same time. The power available from VIN will be split between the boost output and the battery charging current. If the load on the boost is more than what…
We still waiting for a large enough customer to want the bq24140 in QFN.
The IC in development is single input with up to 1-A OTG current and 3A charging current. It is scheduled to release at the end of this year.

Part Number: BQ27421-G1 Other Parts Discussed in Thread: BQ24140 , Hello,
Currently, we get the battery percentage by reading the StateofCharge() of the gauge. But if the battery capacity loses after a long time, can we still get 100% from the StateofCharge…
Hello Sonoki-san,
The bq24140 is currently the only option that can do both charging and provide OTG output at the same time.
Could you provide more details on the application? What is the target charging current and OTG output current? Please note…
