Part Number: BQ24090 Hello,
testing the BQ24090 Li-Ion charger I stumble over the following problem: After plugging in the 5V source, the CHG indicator doesn't go low (the connected LED doesn't turn on) and both voltage on the battery and voltage on…
Part Number: BQ24090 Other Parts Discussed in Thread: TPS22914 Hi,
Greeting!!
As you see below image, I m using NPN transistor as a switch control for the input path will that adversely affect the charge IC?.
The Reason for the switch is given below
As you…
Part Number: BQ24090 Hi, team,
My customer used bq24090 in one of their project. They set fast charging current to be 800mA, connected an 8 ohm load on battery as a load to discharge at the same time when they were charging the battery. Battery iniital…

I use BQ24090 charge the lithium battery,the sch is BQ24090 SCH.zip
when the battery is charge to 3.9V,pull out and insert the adapter multiple times,I found BQ24090 CHG LED is always off and the input current jumps between…
Part Number: BQ24090 Hi,
May I understand if output of BQ24090 is tristate when not charging? There is an option to add alkaline battery and no blocking diode is added.
If blocking diode is added, then the BQ24090 has to be higher than 4.2V to charge…
Part Number: BQ24090 Other Parts Discussed in Thread: TPS73801 Here's the scenario: I've got a circuit that uses BQ24090 to charge a a Lithium 18650 battery which in turn runs a circuit. We were using unprotected cells, and running them into the…
Part Number: BQ24090 hi,
From table 1 listed in Bq24090, at first pluging in adapter, if battery is not full charged, CHG/ pin will be always kept low even battery temperature is higher than 45 celsius degree. is it right?
