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…

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.

Hello team,
I received questions from the customer.
1. Is it possible to turn off the Automatic Power Path function?
2. How should Q4 be selected?
3. Is the zener diode on the SW pin optional?

Part Number: BQ24172 Hi Sir,
we found that pin_20 REGN seem have low impedance phenomenon,
is there any problem with this schematic? what is the reason for the low impedance od REGN pin?

Part Number: BQ24172 Hi everyone,
We are experiencing some manufacturing issues at our EMS, on a BQ24172RGY:
For thermal dissipation the BQ pad is equipped with 15 vias, tented on bottom side. During wave soldering for through hole components, heat seems…
Part Number: BQ24172 Hi team,
In datasheet, the wake current is typically 125mA under the condition of Rsense=10mohm. Since customer want to set the fast charge current to 200mA, they will choose a larger sense resistor like 25mohm or 30mohm.
I was wondering…
Part Number: BQ24172 Hi team,
In datasheet, fast charge timer range is 1~10h. Customer met an issue that their battery is large and they need fast charge time longer, like 12~13h. Now customer connect 0.147uF capacitor to TCC. The question is that if…
Part Number: BQ24172 Hello, TI expert
It seems the battery reverse discharge to the adapter in our custom design. My question is whether the high side mosfet in BQ24172 is off when it is on sleep state.
And the schematic design showes above, is there…
