Part Number: BQ24090 I'm designing a lithium battery charging circuit and I'm using BQ24090. My schematic as below:
I am expecting to have 500mA charging current at 5V, however, I am only able to get 400mA. My lithium battery is at 3.68V and…
Part Number: BQ24090 Hi, Greetings. Our customer want to know the meaning of "Disconnect after Detection" statement found on the simplified diagram on the page 1 of the datasheet. I would appreciate your support for this. Looking forward to your…
Part Number: BQ24090 Goodmorning, I am using the BQ24090 and I know that it has 2 pins for status: PG and CHG and the fucncion of them are very clear.
But is it possible to match some information about a failure of charging the battery in order the detect…
Part Number: BQ24090 Hi,
We've been using the BQ24090 for years in a few designs and it's been pretty solid, with thousands of units in the field. With a new design variant I'm seeing some weird behavior that I'm having trouble understanding.…

hi Engineer:
My circuit diagram is shown in the figure above.
USB plug in to charge the battery.Testing 5V current is only 20mA.The battery is charging at a very slow rate.The current battery voltage is 3.8V.
ISET2 is connected to…
Part Number: BQ24090 hi Engineer:
Use BQ24090 to charge battery 1A.
ISET uses 540 ohm resistance.
BQ24090.The chip is very hot when charging.
Can it be used for a long time?Will it affect the life of chips?
Thanks!!!
Part Number: BQ24090 Other Parts Discussed in Thread: BQ24095 , BQ24092 , BQ24093 , BQ24091 Dear Sir,
BQ24090, I put 10k on the TS, it doesn't works for some board, but if i change to 100kohm, it works, as i know BQ24090 should connect 10k on the TS pin…
Emilija,
So sorry for the confusion. Since the heading refers to BQ24090 but the questions are about BQ25606 and holiday absences, our support team got confused.
Regarding what happens to the output if there is not enough current to supply minimum…
Part Number: BQ24090 Hi Team,
Can you please confirm BQ24090 is compliant with below requirements. If not can you suggest part which meets this.
UL 2595 Ed.2
CSA C22.2 No 0.23 Ed.

Part Number: BQ24090 Dear Forum,
we would load an Li-accu with the BQ24090.
The issu is that there is a Schottky-Diode before the positive pin of the accu. So we can connect the output of the BQ24090 only to the diode with an voltage drop of about 300…
