Part Number: BQ24650 Hi,
We have an electronic board in production with the BQ24650 for a maximum charge current of 4A (using a 6.8uH inductor and 10 milliohm sensing resistance). This board works perfectly, with excellent performance and reaches the m…
Hi Jeff,
I appreciate your comments, but I will try to be more concrete on the question to which we seek an answer.
Our Vmp is of 17V defined by resistances of 1%, so that in the limit we can have 2% of error, that is a Vmp of 16.66V.
Then we used the…
Part Number: BQ24650 Hi,
Is there an application note on how to connect two identical solar panels connected in parallel to a single BQ24650?

Under the same configuration, the charging voltage of one device shows a green waveform as shown in the figure below, and the correct waveform is shown in yellow.
Is the solar charging chip faulty, or the minimum charging voltage…

Dear sir,
I want to charge Orange 18650 Li-on Battery pack 6 cell , 22.2v, 3c, 10,000mAh by using BQ24650 for 1A charge current, I am using all Resistor capacitor components as per TI datasheet instead of MOSFET Si7288 . When battery…
Part Number: BQ24650 Hi,
We have a PCB that allows the possibility to configure the charge termination by assembling a 0R resistor between TERM_EN and Vcc, or between TERM_EN and Gnd.
In the new assembly configuration, we do not have 0R resistors, and…

The customer design with BQ24650. T he input power is 21V, the current is 4A, and the battery is 12V lead-acid battery. When No-load and without battery the output voltage is 13.8V.
There is no charging current when the battery…
Part Number: BQ24650 Other Parts Discussed in Thread: BQ24166 , TPS2121 , BQ24210 I am looking at designing a 1 cell lithium ion battery charger that can be charged from either a solar panel or a standard USB port (charge current under 1A).
I am looking…
Hi Mike.
Here is the current schematic.
And the design spreadsheets, I am sending again if you want to verify.
