Hello,
We are using BQ24071 to charge a Li- pol Battery of 3.7V/1050 Ah with the below mentioned configuration
MODE Pin is tied to GND to enable USB mode,
ISET2 is tied high to limit the input current to 500mA using a 2K resistor.
ISET1/Rset is tied to…
Other Parts Discussed in Thread: BQ24071 Hello,
We are using the BQ24071. We have MODE tied to GND for USB mode, ISET2 is tied high to limit the input current to 500mA. ISET1/Rset is 2.15k. DPPM is 31.6k.
If we increasae the temperature above our thermistor…
Other Parts Discussed in Thread: BQ24071 I bought a BQ24071 circuit from TI and I have a doubt testing it: How can I make BQ24071 with 6.0 Volts in the output when it is only with a lithium battery of 3.7 Volts without the input source? I'mm in trouble…
Other Parts Discussed in Thread: BQ24071 Dear all,
BQ24071 is configured AC mode, and TMR is connected to Vref, Rdppm is set 36k ohm, IN power is 12V, battery haven't been connected to the BAT.
Three tests is done as follow:
1. Load is 40 ohm, the…
Other Parts Discussed in Thread: BQ24071 , BQ24070 , BQ24072 Dear All,
BQ24071 is used in my design for power management.
5V and battery can power the system normally.
But the 5V can't charge the battery.
Would you please tell me the maybe reason…
Other Parts Discussed in Thread: BQ24071 When using a Keithley 2308 battery charger simulator, the BQ24071 appears not to be meeting the spec. However, in practice, when using Li-ion battery the BQ24071 meets spec and there are no strange behaviors seen…
Other Parts Discussed in Thread: BQ24071 Hello,
I'm using the bq24071 to charge a lithium battery with 4000 mAh of capacity, the power source comes from a solar panel which has a working voltage of 4.8V and a working current of 560 mA. I'm using AC Mode…
Other Parts Discussed in Thread: BQ24071 , BQ24070 The half charge current mode of the BQ24071 and it doesn’t seem to work on the eval board.
I’ve got 4.3V fed into the AC supply input. No load on the output. A battery sitting at 3.0V, and…
Other Parts Discussed in Thread: BQ24071 , BQ2002 Is it possible to use a bq24071 to charge a 3 cell NiMh battery (3.6V) ???? The charge profile looks like could work at the expense of never detecting charge termination....
any ideas?
Other Parts Discussed in Thread: BQ24071 Hello,
I am using the BQ24071 IC for charging a single cell li-ion battery from a solar panel. I would like to know if it is possible to set the Vdppm voltage threshold around 5.5V (MPP for my solar panel).
