Part Number: BQ24040 Hi.
I am using the BQ24040 to charge a lithium-ion battery. Figure 1 shows the circuit diagram. An NTC thermistor (10kohm, B=3435) is connected to the TS pin. To verify the TS function, I conducted an experiment using a temperature…
Part Number: BQ24040 Tool/software: For BQ24040DSQR ISET pin The resistor value used to program the IOUT to program (fast charging) current according to this equation : RISET = KISET / IOUT
If I set the ISET with higher c-rating of the battery Does…
Part Number: BQ24040 Tool/software: Dear TI Engineer,
We have one question about the charging temperature of BQ24040. That is, the battery was integrated a 10KNTC which corresponds to a B value of 3435. If we directly connect the TS pin to the NTC…
Part Number: BQ24040 Hello,
I'm looking for an IC that will monitor battery voltage level over time. It's for a prototype wireless system. I'd like to be able to see how to device uses power over time. I'm planning to put the rechargeable battery under…
Part Number: BQ24040 Other Parts Discussed in Thread: BQ2040 Tool/software: Hello,
After removal of the battery and charging port connected to the circuit from VIN(usb power), BQ2040 continues to supply the circuit from VOUT and does not cut off the…
Part Number: BQ24040 Hi Team,
Using BQ24040, If there is no battery connected to the system, does the USB still power the system while periodically checking for a battery? If so, what current is supplied to the system? Is this limited by ISET2? Regards…
Part Number: BQ24040 Hi team,
I am using the BQ24040 and have a question regarding leakage current when the IC is not powered (VIN = 0 V).
The datasheet specifies IOUT(PDWN) with a maximum of 1 µA for leakage from the battery to the OUT pin. In…
Part Number: BQ24040 Hi Team,
Posting on behalf of our customer.
I am designing a system that is powered by a 150mAh LiPo battery. I am using the BQ24040 to handle the charging of this battery. My system load when idle will only draw a few mA, but…
