Part Number: BQ24172 Hi,
The below image is our schematic design
Here, we are giving 12V input to the power connector. when I checked voltage after Q6(ACFET),voltage is 6V. Why 12V is reduced to 6V?
Please help me resolve this.
Part Number: BQ24172 Hi ,
Im using BQ24172 charger to charge two 3.7V batteries connected in parallel. The battery charging voltage is 4.2v and the charging current is set to 1A.
In this setting, will BQ24172 charge the batteries with charging current…
Part Number: BQ24172 Hi,
In our design, BQ24172 will be used to charge a battery with ISET = 2A and VBATT= 4.2V. Adaptor input voltage will be 12V and load will take around 1A. Please tell me with this configuration, how current will BQ24172 take to charge…

Hi,
Early we have used BQ24172 to charge 2p 3.7v battery by setting battery voltage as 4.2V.
No we want charge 2s 3.7v battery with same circuit. For that, I just have set…

I have electrical questions about this battery charge controller BQ24172
We have a charging base with 5 of these controllers that can charge Li-Ion batteries. We are seeing failures in the…
Part Number: BQ24172 Hello,
If I want to disable the DPM function for bq24172, may I do it like the red remarks, which I did in the screenshot as below?
1) Replace RAC with a short, remove C11;
2)Remove R4 and R5, and connect VACSET to VREF.
Thanks, …

Hello, TI experts
BQ24172 plays the role of Li-ION battery mangement in our design. When the battery is full of charge, it seems overcharge may happen sometimes. And the voltage waveform at this time showes in the picture below…
Part Number: BQ24172 Hello, TI expert
On BQ24172 datasheet, the typical schematic on page1 ultilize two FETS Q1 and Q2, and so called ACFET and RBFET. But they are sharing the same source and gate pin, so they are both on or off simultaneously.
1. On…
Part Number: BQ24172 Hello
I want to pull up the TTC pin to VREF to disable the safety timer, is it OK to connect it directly to VREF?
Thanks and best regards.
