Part Number: BQ21040 Tool/software: Hi Team,
I am planning to use two BQ21040 ICs to charge two separate 400mAh LiPo batteries, each at a charging current of 500mA, from a single 5V USB-C power source. To achieve this, I intend to set the CC lines to…
Part Number: BQ21040 Hello TI team,
We are using the BQ21040 to charge a 2.6 Ah Li ion battery. We have two LED's connected to the CHG_N with a 1.5 K-ohm pull up resistor to both LED's. We've noticed if the battery is connected to the charger and…
Part Number: BQ21040 Other Parts Discussed in Thread: BQ25618 , BQ25628 Tool/software: We are charging 1 li-ion battery, 138mAH with BQ21040DBVR. For an unknown reason, on rare occasions, upon connecting the charger to the battery, when the battery is…
Part Number: BQ21040 Tool/software: Dear Texas Instruments Support Team,
I hope this message finds you well. I am working on a project that requires the simulation of the BQ21040DBVR and MP2338GTL-P, and I was wondering if you could provide a SPICE…
Part Number: BQ21040 Tool/software: Hello All,
We are using BQ21040 to charge LiPo battery with charging current of 150 mA from a input supply of 5V. The resistor value of 3.6K was chosen for that. Ts terminal was connected to 10K resistor as temperature…
