Part Number: BQ24155BQ24155RGYR is used to charge a 500mAh Li-po battery. Since this is our latest design we would like to hear from you before sending it to fabrication. Those green colored lines are bottom layer traces connected through vias. Please…
Part Number: BQ24155 Other Parts Discussed in Thread: EV2400 , Hello guys!
We have TI's EV2400 and we are using BQ24155 charger IC in our design. I've searched if BQ24155 is supported by Battery Management Studio but I couldn't find any info on that…
Hi Jeff,
Thank you for the answer and testing. We moved the initialization forward in time and now the charger boosts the voltage to 4.2V and the battery unlocks.We also reviewed again the BQ24155 datasheet and fixed out initialization. Now it is:
Turn…
Part Number: BQ24155 Hi,
According to the datasheet, battery discharge current in high impedance mode could be up to 20uA.
My goal is to reduce this current to less than 1uA. I don't need charger functionality at high impedance mode, so it would be nice…
Part Number: BQ24155 Other Parts Discussed in Thread: BQ24210 , BQ24250
20-V Absolute Maximum Input Voltage Rating
6-V Maximum Operating Input Voltage
What is the difference between these spec's ?
Can I charge a Li-po battery from a 7V solar panel…
Part Number: BQ24155 Other Parts Discussed in Thread: BQ25606 bq24155 will this part supply power to the load when the battery is disconnected?
Thanks.
Part Number: BQ24155 Dear Specialists,
My customer is considering BQ24155 and has a question.
I would be grateful if you could advise.

I would like to use 3.3V for I2C(SCL, SDA) Voltage.
In the meantime, test condition of electrical specification…
Part Number: BQ24155 Hi,
We have noticed that sometimes when the charger is finished with charging and we remove the device from the power supply. The VBUS input voltage (instead of dropping to 0V as normally happens) rises to +6V
It only seems to happen…
Part Number: BQ24155 Hello, everyone!
I develop a device with BQ24155 as a charger for built-in Li-ion battery. But after start using this charger (we used a linear charger previously), a problem was noticed. Sometimes (several times per day with no visible…
Hi Victor,
I am not aware of a known issue related to this particular device's structural integrity. All WCSP packaged ICs are somewhat fragile. If FA is desired, then you or the customer can submit through the normal TI return process on the TI website…
