Hello Team,
Our customer is evaluating the BQ24090. for battery charging. The customer faces an issue when battery is discharged: “I’ve an issue with the Evaluation board BQ24090EVM…
Other Parts Discussed in Thread: BQ24090EVM Hi,
I am doing a school project and I am planning on using the BQ24090EVM to charge a battery. In the user guide, under test procedure, it has a 4.2V battery listed. I am having difficulty finding a battery…
Part Number: BQ25101 Other Parts Discussed in Thread: BQ24090 , BQ24090EVM Hi Team,
The pin description of /CHG tells it goes low (FET on) when charging and open drain (FET off) when no charging, some tests don't match the description:
The NTC is…
Other Parts Discussed in Thread: BQ24090 , BQ24090EVM Hi,
I evaluated bq24090 with additional resistor on BAT+ that simulate long wire of battery pack. Then I confirmed charging failure as attached. I guess that the charging is stopped due to output…
See inline reply below, (measured on BQ24090EVM)
1.) Vin=5.045V and Vout=4.016V on the EVM board
2.) Voltage at ISET pin = 1.49V
3.) Double check the ISET2 jumper should be HI (500mA) position = Yes
We are getting same results on our BQ24090 designed…
Hi Yuanchen
Q1 - The two tables are different test boards. 8.5 is a traditional board JEDEC High-K board while 8.5 is newer test methods IC Package Thermal Metrics, SPRA953. This value is highly dependent on the PCB construction, copper area thickness…
Adam,
You only need to order either the BQ24090EVM or the BQ25040EVM since they perform the same function with different features. Also, be sure and download the user's guide (and datasheet) for any EVMs you order: BQ24090EVM , BQ25040EVM and TPS61200EVM…
Other Parts Discussed in Thread: BQ24090 First of all, I am using BQ24090EVM-001 evaluation boards, which I set the RISET = 1 kOhm (current is around 540 mA); Enabled TS with simple 10 kOhm resistor (no TS function or connection to the battery); ISET2…
