Hi Pavel,
Below image is a screen grab of the TI GUI showing all current register statues. I have tested with your exact register settings, as well as, closely replicated your input voltage and battery voltage. The BQ25896 charges at 0.96A as expected…
Hi Patrick,
Please see my comments below.
With the device in ship mode (when you set BATFET_DIS) QON pin voltage being driven below 0.4V for typical 1 sec will result in BATFET turn on.
Patrick Dight said: The BQ25896 is keeping QON at 2.2v. What size resistor…
Part Number: BQ25896 Trying to track down a problem involving 2 BQ25896RTWRs on two separate boards (out of 50-100 produced).
Both ICs have literally smoked, as shown in picture.
Prior to smoking, a "clicking" noise was heard coming from battery charge…
Part Number: BQ25896 Other Parts Discussed in Thread: BQ25895 Hi,
In my circuit 12V is the Vin that is used step down to 5V and then 3.3V for powering the microcontroller and other peripherals. Also 12V is used to charge the battery.
Whenever the 12V…
Part Number: BQ25896 Dear Ti support team.
I made a battery charger system by BQ25896. Does BQ25896 support to hot plugin of battery pack when dc power is suppleid ?
The battery pack is having +,TH,-.And single cell.
Battery connector doesn't have sequence…
Hi Florian,
Let me help to clarify.
There is a known bug which results in the behavior you reported where BQ25896 device gets in a locked up state and an adapter plug in won't power on the outputs as expected. The root cause for this bug is an incomplete…

Hello,
I want to use the BQ25896 in a hot ambient environment (40°C). Our battery has a max charge temperature of 45°C and contains a 10KΩ Thermistor with a Beta of 3435…
Part Number: BQ25896 Hi ,
we are using BQ25896RTWR for battery power management. we have set the input current limit to 500 mA by connecting external resister (787 ohm) at ILIM pin.
Here my question is, How to verify that the IC actually draws the current…
