Part Number: BQ24725A Dear Team,
Please find schematic for your reference.
Our measurement as per below.
The ACDRV pin does not have a normal output and the voltage is approximately 0.0V.
Without battery
VCC = 12V
ACDET = 2.6V
ACN= 0V
ACP= 0V

Part Number: BQ24725A Hi
The customer design with BQ24725A, the problem is the the actual charging current is less than t he configuration charging current.
The resistance of the ILIM pin is 316kΩ/100kΩ.
The charging current configured in the…
Part Number: BQ24725A This is a follow up to an earlier thread on the same issue. I have been able to change bit one of the Charge Options register (0x12) from '1' to '0' and have observed the same issue previously mentioned. On some boards, the AC Power…
Part Number: BQ24725A Other Parts Discussed in Thread: BQ24725 I have an application with a BQ24725 charger that does not reliably turn on the AC Adapter Power path. On some boards, everything seems to work as intended so I may have a manufacturing defect…
Part Number: BQ24800 Other Parts Discussed in Thread: BQ24725A Hello Sir:
We want to change better LT items for our products.
We found BQ24800 which functions are similar with BQ24725A.
Do you have some simple guide line to compare with that two items…
Hello Randy,
Randy Holmberg said: What recommendations would you have for an application where the battery can be plugged / unplugged anytime?
You mentioned in you first question that you had an MCU that would be able to disable charging.

Part Number: BQ24725A We have a development system with an SMBus battery and the BQ24725A.
We interrogate the battery and a charge current of 4000mA is requested at a voltage of 16800mV.
When we write these values into the appropriate registers, the battery…
Part Number: BQ24725A Other Parts Discussed in Thread: BQ24725 , BQ24750 Hi Team,
My customer plan use BQ24725A as battery charger only not need DPM function, system power will separate from VBAT but connect to input power directly.
Customer still need…

Hello, TI. . I would like to disable BATFET when ChargeOptions()[LEARN] bit is 0 and enable when ChargeOptions()[LEARN] bit is 1. My battery is 2S. Can you give some explanation why bq holds BATDRV pin at non zero voltage even LEARN bit…
Part Number: BQ24725A Other Parts Discussed in Thread: BQ24725 , BQ24753 hi , TI's experts:
There is a doubt about bq24725,there is the thing.
According to the describe from the bq24725's datasheet,to aviod the voltage spike at VCC pin maybe beyond…
