Part Number: BQ24091
Hi, TI expert
Customer is reviewing BQ24901, and there is a recommendation for a vendor and part number for NTC.
In the datasheet of BQ24091, there is the following information.
Even if you search for 10-k NTC and from the same…

Hi, TI expert.
According to the BQ24091 datasheet, I understood that using ß=3370 out of 100K NTC would allow setting from 0 to 45°C without additional external resistors.
However…
Part Number: BQ24091 Hi,
I want to use BQ24091 to charge 3.7v 2500mAh lithium ion battery. My queries are:
1.In Datasheet BQ24091 out voltage is 4.2. Can i use 4.2 OUT voltage output to charge 3.7V battery placed in J11 connector place. by using 540mA…
Part Number: BQ24091 Hello,
In two of our projects we are using the BQ24091 to charge a 80mA lipo battery but for some reason it doesn't react like expected.
I have set the Riset resistor to 10k7 in order to have 50mA of fast current.
I have ordered…
Part Number: BQ24091 Hi,
Is it possible to connect an NTC to the TS pin and to the MCU at the same time?
In that way, I could use the NTC to detect when there is a problem when charging the battery and when the device is used I could monitor the temperature…
Part Number: BQ24091 Dear，
We layout a board to test BQ24091 and meet some problem.
When we set pin7 ISET2 to High, sometimes there is no Low status output in P8 CHG during chagring stage.
If we set Pon7 float, the status of P8 is ok.
And we have try…
Part Number: BQ24091 Hello,
When I set Iinmax = 1A, Ichg = 1A but Vin source connected to Note PC (Iinmax = 500mA)
1. Can I use Fast Charge (1A charging)? or charge current is limited only 500mA?
2. If Battery pulled 1A by force, It can make Host(Note…
Hi Andy
Do not have reference design for BQ24040 to use 100k NTC vs standard 10k.
The BQ24091 and BQ24093 will support 100k NTC they are similar devices but different package.

Hi. I am experiencing a strange problem with BQ24091, when charging a standard single-cell Li-ion battery.
After the first charge cycle (battery is correctly charged up to 4.20v), the power good led…
What current source setting do you have? The BQ24090/2/5 uses 50uA with 10K (which is 500mV) and the BQ24091/3 uses 5uA with 100K (also 500mV).
If you have the 10K with the 5uA, then you would have only 50mV which is close to the voltage of 60mV that you…
