Part Number: BQ24172 I selected the BQ24172 to see if I could charge a 12V Nimh battery pack using a normal car's 12V line as input. Based on the datasheet this seems like it should be possible, but I tested it in two independent circuits I had created…
Part Number: BQ24172 Hello,
The formula for taper current is given as Iterm = Viset / (200*Rsr). With the minimum .12V on Viset and a 10ohm Rsr, this gives me 60mA for termination.
However, there is this note in the datasheet:
So is there…

Hello,
We are using BQ24172RGYR IC in our design to charge 7.4V 13500mA Lithium Polymer battery.
The input voltage is 12VDC and input current is set max to 1.6A (ACSET) but its only using 1.3A during charging.
The battery…

Hi,
I am going to design BQ24172 based battery charger for LifeP04 3S batteries, is it BQ24172 support to this LiFeP04 batteries if not please suggest equivalent part..
Part Number: BQ24172 Hello,
BQ24172RGYR recognizes that Ni-MH is also compatible if the end of charging is detected by an external circuit. In order to charge Ni-MH 3 series (4.8V max), the input power supply must be at least what voltage ?
Regards…
Part Number: BQ24172 Hello,
When the battery depletes below a certain level, lets say ~3V. What state does the charger go into? I think this is sleep mode buts its unclear.
During sleep mode what is the status of Q3, is it off to disconnect the battery…
Part Number: BQ24172 Hellow,
I am thinking about how to generate a Power Good signal for the adapter input on a system using the BQ24172. If I look at the common source of the input power switch, I think I can make a Power Good decision. Please let…
Part Number: BQ24172 I would like to know how to check if the set charging voltage is output normally.
Experimentally, I measured the charging voltage by the following method.
１. With the battery connected, turn on the power and start charging.
