Part Number: BQ24725A Other Parts Discussed in Thread: BQ40Z50-R2 , BQ24800 , BQ24780S Tool/software: Customer was looking for a charger for a 2 cell application, Vin=12V, output voltage=8.4V, charging current within 1.2A.
And they also used bq40z50-r2 to…
Part Number: BQ24725A Tool/software: Hi Christian,
Is it optional to use the ILIM pin as an input comes form from MCU which in turn :
1. Drive it to GND in order to cut off charging.
2. Release it to H-Z to let the resistors voltage divider on the ILIM…

I'm intending to use the BQ24725a charger in my design for charging in up to 9A charging current and voltage 12.5v.
According to the Typical Application and also…
Part Number: BQ24725A Tool/software: Hi team,
the current sense between ACN and ACP will limit the input current. My question is that how long time overcurrent is able to be limited? In customer board, we found that us level overcurrent is not limited…
Hi Aya,
We couldn't provide waveforms to you because of we have only 2 channel DSO. Anyway my issue is resolved after purchase the EVK module.
There are more than two difference found from EVK to datasheet.
I would like to thanks for your support.

Part Number: BQ24725A I have a couple questions regarding the TI BQ24725A battery charger controller IC. Details are provided below.
From what I can tell, I believe that the lowest power consumption state for the IC is when VCC is disconnected per the…
Part Number: BQ24725A Hello,
Something in that example design appear in the BQ24725A datasheet is not clear:
The RBFET is connected in a way that Vs>Vd when adaptor is supplying the system. Since it is N-channel (FDS66880A) How will it conduct when adaptor…
Hello Ohad,
I'm sorry for the confusion, I hope this clears things up.

Part Number: BQ24725A 1. When switching from battery to adapter, BQ24725A might show a delay of 150ms and then 1.2s (changeable) as per the datasheet. How much time does it take to switch from adapter to battery when adapter turns off ?
2. Is there an…
