1) When there is no battery, the charger will perform the battery test procedure by injecting current into the battery pin entering the capacitor. This will cause the capacitor to charge to vbatreg and discharge.

Part Number: BQ24074 Other Parts Discussed in Thread: BQ24072 , Hi Experts,
Good day. I would like to ask confirmation about design help on your end for this case from client:
"1.) The concern in your response to case CS0746349 was that the device…
Part Number: BQ24074 Hi, I am looking at the bq24074 datasheet, and for a number of pins there are internal pull down resistors. Still, the text states "do not leave pin XX unconnected to ensure proper operation". If I am satisfied with the default settings…

Hi,
We are using BQ24074RGTT for Li-Po battery charger in one of our designs. lately we have observed some of the IC are not generating VOUT voltage with input being fed form USB supply. Is this situation observed in where. We…

Hi TI experts,
My company is mass-producing boards with BQ24074 applied.
The BQ24074 burnout or no output symptom occurred in around 400 out of a total of 5000 products.
Please check the circuit design and give me some guide…
Part Number: BQ24072 Other Parts Discussed in Thread: BQ24074 , Hi,
The customer is using BQ24074.
Due to the delivery date problem, I would like to change to BQ24072.
There is a difference in the pin 15 functions of the two products, but we believe…
Part Number: BQ24074 In my circuit it might be neccessary to cap some overvoltages. The battery would be a safe place for dumping a couple of milliamps (unless it is already fully charged, even a couple of hundred mA). Assuming I direct those currents…
Part Number: BQ24074 Hi team,
Here's an issue from the customer may need your help:
1) As shown above, the TS connects R520 to GND, and the internal NTC of the battery is 10K. What is the actual NTC temperature range monitored?
2) ITERM is connected…
Part Number: BQ24074
Hi Experts,
Good day.
Can you share us why the notes here from D/S of subjected component tells that such pin is internally pulled down but a follow up notes "Do not leave unconnected"? Does it mean the 285kOhm is not enough…
Part Number: BQ24074 Dear Expert
When BQ24074 is in use, we set 5/V0.8A charging. When the external input current is not enough for 0.8A charging, the 5V voltage will be pulled down. Is this A normal phenomenon?
For example, if the battery is charged…
