Part Number: BQ24074 Tool/software: Hey, I bought the Adafruit Solar charger for testing the BQ24074 IC and I had A LOT of problems with it. Now I am using the EVM Board to get my setting right for the PCB print. Finally I am nearly done. But there are…
Part Number: BQ24074 Tool/software: Hey,
I am thinking about how to set up my safty timer. I am using a 1S -Lipo (3.7 V, 0.150 Ohm). Right now i am charging at ~900mA and I_TERM is set to default. The Lipo is fully charged after~ 2hr. The fast charging…
Part Number: BQ24074 Tool/software: Hello, I am currently working on an hand held device that can be powered by either an external connector, or trough a single rechargeable battery AA. I ve been reading a lot, datasheets and discussions. My concern is…
Part Number: BQ24074 Tool/software: We're looking at using a solar panel as the input source and it may provide 2A or more. We want the panel to be able to provide full system power and possibly charge on cloudy days. We see the 1.6A max input current…
Part Number: BQ24074 Tool/software: I'm designing a circuit with the BQ24074 charger and followed the datasheet's suggestion of adding a 4.7uF decoupling cap to the output. However the 3.3V LDO I plan to connect to the output also recommends a 10uF input…
Part Number: BQ24074 Hello,
Quick question on the charge profile
Whilst plotting the charging characteristics we noticed that the charge seams to turn on and off is this normal ?
Just trying to understand what and why
The voltage and temperatures are…
Part Number: BQ24074 Hello,
Whilst testing a customers item for compliance, i have noticed that is the battery is discharged to the point of that battery 'Deep Discharge Protection' operates and disconnects it self.
When the power is restored…
