Part Number: BQ24090 Other Parts Discussed in Thread: BQ25171-Q1 I would like to power the BQ24090 with a regulated 12 Volt DC wall adapter. I read the specifications, but there appears to be some confusion as whether this can be done. On Figure 2, the…
Part Number: BQ24090 Other Parts Discussed in Thread: BQ25170 Hi TI expert
we have done design with super cap charger 4.2V with BQ24090
Now, we need to change supper cap to LIC (lithium-ion capacitor ) and the ref voltage charger is only 3.8V.
So the…
Part Number: BQ24090 Hi!
I would like to check if the safety timer on the BQ24090 is working fine.
In the test the cell is charged and discharged at the same time (i try to keep cell voltage on 3.3V). I detected that charging did not stop after 10 hours…
Part Number: BQ24090 Hi Team,
My customer requested confirmation on whether the BQ24090 complies with M.4 of IEC 62368-1-2014 by cutting the charger off for battery temperature outside 0 to 45 Deg window?. Please help with you inputs.
Thanks in advance…
Part Number: BQ24090 Hi
I will use the BQ24090 charger in a design that needs a wake-up signal when the charger is connected to a power source. I would like to know if the CHG pin always indicate charge when the charger is powered up? What happen if…
Part Number: BQ24090 Hi
I would like to use the NTC resistor that are connected to the TS pin to measure cell temperature when our application is not charged. In the datasheet I find this. The bq2409x family is in power down mode if the IN pin voltage…
Part Number: BQ24090
C6 - 1uF
R7 - 536Ohm
R8 - 2.2kOhm
R9 - 5.6kOhm
R10 - 2.7kOhm
CHARGE_EN - 1.892v-1.352v or GND controlled by OR Gate (SN74AUP1G32DCKR)
I just wanted to check my schematic because the datasheet regarding the TS pin could be more clear…
Part Number: BQ24090 Hi,
I need to monitor the battery voltage as we see in the mobile.
Let me explain with the help of an example.
Let us say we have battery voltage at 50% and I'll get the respected readings by ADC program to micro-controller. Now if…
