Part Number: BQ25896 Hi
We use a USB port as power source to charge battery via bq25896.
set vindpm=4.5V and ILIM=700mA
Our question is why when the vbus voltage hit the vindpm then charger will stop charging instead of reduce current?
what is condition…
Part Number: BQ25896 Hi team,
My customer has one question about VBUS voltage hysteresis value?
Testing condition:
The VINDPM=4.5V and customer is trying to reduce VBUS voltage lower than 4.5V.
Based on our observation, when VBUS voltage is lower than…
Part Number: BQ25896 Other Parts Discussed in Thread: BQ40Z50 Question 1 - REG10 TS voltage: slusc76c manual (bq25896 documentation) describes register content as ADC convertion of TS voltage with values from 21% to 80%. Chapter 9.2.7.5.1 describes the…
Part Number: BQ25896 Other Parts Discussed in Thread: BQ25895 , TPS745 Hello,
At least two other people before me have asked for an accuracy specification of the ADC in the bq25896, but received the surprising answer that TI doesn't have the data: …
Part Number: BQ25896 Hello,
In the datasheet, under 9.2.16.7 Multi-Read and Multi-Write, it says "REG0C does not support multi-read and multi-write".
Could you please be more specific about its behaviour?
REG0C is a read-only register, so supposedly…
Part Number: BQ25896 Hello,
"When termination occurs, the status register CHRG_STAT is set to 11, and an INT pulse is asserted to the host. Termination is temporarily disabled when the charger device is in input current, voltage or thermal regulation…

Part Number: BQ25896 Hi team,
My customer is using our BQ25896 for their
May I know the accuracy of termination current if ITERM register was set for 64 mA in BQ25896. In customer's application, 125 mA termination current was measured with ICHG register…
Part Number: BQ25896 Hi Sir,
Our customers using BQ25896 for their tablet product, and encountered a problem that a low pulse will occured with a period of about 40s. By checking the data sheet, we found that this problem is caused by the default 40s watchdog…
Part Number: BQ25896 I have built a 8P Li+ 18650 Battery pack and charging it through a MPPT Bq2589x Charger IC, the Issue I have found is the battery pack is not delivering any Voltage below ~3.5V, I suspect any Balacning to be done for the batteries…
