Part Number: BQ24172 Hi team,
My customer is using the BQ24172 now. The output is 12v, we want to check the min input voltage.
The datasheet says the Dmax can be 97%. Do you have some suggestions about the input voltage?
Thanks.

Part Number: BQ24172 Hi team,
My customer is using the BQ24172 now. They want to remove the battery detection function and get the no output when removing the battery. Do we have some methods to achieve it?
Thanks.

Part Number: BQ24172 Other Parts Discussed in Thread: BQ24170 Hello, The system examples in the datasheet for the BQ2417x, in figure 23 the system voltage is taken prior to the sense resistor Rsr, and in all of the other figures the system voltage is…
Hi,
I do not have any test data without the diode. In other devices, the diode not only improves efficiency by up to 2% but also reduces subtrate injection noise which can affect regulation accuracy in the 10% range if not more.

Part Number: BQ24172 Dear Sir,
I am using BQ24172 as our battery charger. The Adapter source is 30W MAX.
Currently, we are charging the battery while the system is working with 17Watt load.
our battery charger specification : Ichmax=2.6A for 2S2P…

Hello, TI expert
The default 10mOhm current sensor resistor results a 400mA termination current. But it seems our battery is not full of charge at this termination current. So is there any way to decrease this current?
Best…
Part Number: BQ24172 Our application has a removable battery. We have 0 ohm connected to TTC (disable safety timer and charge termination -- our MCU is controlling charge termination).
The steps are:
Power up BQ24172 with no battery connected. …
Part Number: BQ24172 Hi,
Is a pull-up register connected with STAT pin internally?
Though it is described on the pin function, there is nothing on the block diagram.

Part Number: BQ24172 Hi,
What is the minimum current of BQ24172?
(I need a minimum current of 80mA).
From the graphs in the datasheet it seems that the current is 0.5A.
However, i am sure that the current may be lower (of course the efficiency…
Part Number: BQ24172 Hi, my name is Sang-Rae Lee.
We have designed our schematic with BQ24172.
There are some questions about fast charge current set value and charge termination related to TTC pin.
[Question 1]
The adapter or USB cable can…
