Part Number: BQ24773EVM-540 Other Parts Discussed in Thread: BQ24725A , BQ24773 Tool/software: Hi Team,
I'd like to promote 4s charger in Vacuum application, may I know the benefit of choosing BQ24773 compared with BQ24725A? I notice that BQ24773 support…
Hello Doan,
Doan sang said: I think it relate to start-up condition of charger controller. When start-up, It will check load condittion at the output, if load higer one threshold, it will off charger.
I don't see this issue when I use an EVM.
Can you…

Hello,
I have designed the proto board using the IC BQ24725ARGRR.
I am giving the 12V Input but cannot get the desired output,
Input :12VDC (+12VDC_JACK)
Output : vary from 1V…
Part Number: BQ24725A Tool/software: Hi TI expert,
I designed 2S charger circuit, input voltage is 12V, system (+SYS_IN after FB23 in image below). is then feed to buck converter to supply load 5V/2A.
The issue is when I plug 12V input to charger to start…
Part Number: BQ24725A Tool/software: Hi experts,
My design uses STM32F103C8T6 interface with charger IC (using SMBUS), through I2C. MCU often freezes when charger switches to charging mode.
I do not understand root cause, please help me explain & fix…
Hello Mehmet,
Thank you for the clarification,
Mehmet Ali İsmailogullari said: Our adapter voltage is the output of an AC-DC regulator, ranging between 17.80-18.30V after the initial moment.
I see no obvious issue with your schemetic that would cause…

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…
Part Number: BQ24725A Other Parts Discussed in Thread: BQ24725 Tool/software: Hello,
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…
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.
