Other Parts Discussed in Thread: BQ24073 , BQ24074 , BQ24075 , BQ24079 , BQ24072 I can I override the BQ24073 charger NTC input with the output of an op-amp? Our battery has a 100K NTC rather than the default 10K value. Will this cause any issues?
Other Parts Discussed in Thread: MSP430F2274 , MSP430F5504 , BQ24072 Hi,
I currently have a rechargeable battery application using the msp430f2274 and the BQ24072 power path management. I need to move to the msp430f5504 for future firmware upgrades…
Hi Zheng,
The only difference is the BATTERY PACK T EMPERATURE MONITORING. bq24072 uses current mode and bq24072T uses voltage mode. Please see pg5, pg28-29 of bq24072 d/s and pg5, pg24-25 of bq24072T d/s for m ore details.
Thanks

Other Parts Discussed in Thread: BQ24072 Hi,
We have a design with a BQ28550-R1 gas gauge coupled with a BQ24072 charger.
The gas gauge gets correctly woken up (turning FETs on) when the charger is connected and it also turns OFF the FETs when the…
Dear QM,
I designed a device with CC2530, which is also need a power management IC.
BQ24072 is used in my design, which is not include an 3.3V LDO, but other voltage, 4V maybe I am not sure.
So I used BQ24072 + LDO(3.3V). You need to choose an…

Hello Nanda,
In my application (BQ24072T) I used ISET=845, ILIM=1.18K and TMR of 10K. I have EN1 tied to Vss via 10K and EN2 tied directly to OUT1 and OUT2. OUT1 and OUT2 are tied together. With an input voltage of 5.11v, I have observed the charging…
Hi Tahar,
In my application, CE is connected to OUT, the OUT is 0V whenever the IN is present or absent, while the CE is also LOW, the chip is disabled. So I need to short the OUT to IN one time(only one time), which make CE is HIGH, enable the chip…
Other Parts Discussed in Thread: BQ24072 , BQ24650 , BQ24640 Need your feedback. My system harvest renewal energy and store it to super-capacitor. I used super-cap so charging rate is fast.
The charge in the super-cap then can be used for charging…
Other Parts Discussed in Thread: BQ24210 , BQ24072 , BQ24073 1a) Hi, what happens if I connect more than one bq24210 chip in parallel to potentially increase current output?
b)If the battery is removed, and is connected still to its parallel load as…
