Part Number: BQ51050B I am using the BQ51050B as a Qi receiver/charger with a single-cell Li-Ion battery.
I have observed a behavior that seems to depend on the internal charging state of the BQ51050B, and I would like to understand whether this is…
Part Number: BQ51050B Other Parts Discussed in Thread: TIDA-00669 , Hi,
I have a measurement setup to check the charging behaviour with some chargers on our circuit, with one of the charger I noticed a weird behaviour and want to try to understand that…
Part Number: BQ51050B Hello,
We have had what I believe to be hardware-related failures on some of our boards. The TI p/n we are using is BQ51050BRHLT.
Here is the schematic for reference:
The battery is a 250 mAh li-po with a built-in protection…
Part Number: BQ51050B Tool/software: Hi,
we want to use the BQ51050B in a design. We don't use a NTC but have a different temperature sensor on the pcb that's connected to our host MCU.
How do we stop the charging from the MCU? Do we need to pull…
Part Number: BQ51050B I'm using a BQ51050B connected to a load that consumes between 0 and 180 mA during transmission. During taper mode, my BQ51050B starts exhibiting this behavior, as shown in the attached photo, where it blinks the charging base and…
Part Number: BQ51050B
As shown in the figure (x-axis 0-100), the current regulation phase curve shows a downward trend. The adapter uses a 5V/2A power supply. What could be causing this?
Is the current regulation phase curve of the BQ51050B equivalent…
Part Number: BQ51050B Hi TI Applications Support,
We're seeing a repeatable end-of-charge issue with the bq51050B wireless power receiver in a wearable sensor product (Li-ion battery, single-cell, PCM hardware overcharge trip at 4.25V ±0.025V). We found…
Part Number: BQ51050B Tool/software: Hello,
I am designing a circuit with a lithium-ion battery and using the BQ51050B for wireless charging. The battery includes a protection circuit , which cuts off the connection when the voltage drops too low. …
Part Number: BQ51050B Other Parts Discussed in Thread: TIDA-00669
Hi,
in our design, we more or less copied the reference layout TIDA00669 as we use the same 7.5µH receiver coil from Wurth. However, our coupling is not great so we measured the inductance…
Part Number: BQ51050B Hi
EPT is not happening at transmittor even after the battery is charged upto 4.18 V without any load to the battery
Please let us know if there is any way we could add an LED indicator for completion of charge at receiver…
