Part Number: BQ24074 Tool/software: Hi Team,
I am trying to understand the working of power IC BQ24074RGTR, i am working on a project where power IC plays crucial role to supply power to our circuit board, here is the part of schematics:
I have…
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 Hi
When my BQ24074 working on pre-charge mode, BAT pin(2,3) voltage is only 1.64V. I tried to remove the battery, the floating BAT pin(2,3) voltage is still 1.64V. Is this normal? Attached is my circuit diagram, please help to check…
Part Number: BQ24074 Hello,
I have a BQ24074 Battery charger IC. How does the voltage level change when the battery voltages the output? (INPUT SOURCE NOT CONNECTED)
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 the…
Part Number: BQ24074
1) The battery charges "successfully" as in, as measured by a DMM, the current into the battery is dropping below the termination current and the voltage is up ~4.2V. I started with a battery at 3.6V. 2) The CHG pin does not…
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…
