Part Number: BQ20Z90-V150 Other Parts Discussed in Thread: BQ29330 Hi TI Power management team,
Our company has used the whole scheme of BQ20Z90-V1.50 + BQ29330 module as our power supply scheme. Now we have a demand to count the number of charging…
Other Parts Discussed in Thread: BQ29330 , BQ20Z70 , BQ20Z90 Hello,
I could see that the input resistor value of PACK of BQ29330 is 10Kohm, R20, in the reference schematics of BQ20Z70, SLUS686B.
However, I could see the different value of the resistor…
Other Parts Discussed in Thread: BQ20Z90 , BQ29330 Dear sirs, good day!
I have a problem with my LION controller based on the BQ20z90+BQ29330 chipset. After learning cycle and after all the steps described in SLUA421A doc BQ20x90 turns off both FETs…
TVS may help, but We have not tried this.
We have not tested the ESD robustness of the PACK+ signal on the EVM. The newer EVMs add a 1 Mohm resistor to the gate of the FET. This may help.
There are no settings in bqEasy for this kind of situation…
Other Parts Discussed in Thread: BQ29330 Hello,
I'm having a problem producing the golden image for a 4s8p Li-ion battery pack using the BQ0Z90 with BQ29330. I followed the steps according to section 2 of SLUA379D. The problem is that after 3 cycles…
Hey all,
I was wondering if it is possible to use the GPOD pin as a general purpose output. I realize this would require custom software. I have heard that the PIN is somehow associated with the precharge function, but the datasheet seems unclear. …
Other Parts Discussed in Thread: BQ29330 I use the BQ29330 in a battery management system, but have a problem with the short circuit function.
I have set the short circuit in discharge configuration register to be 0x0000.
For some reason it does not…
Other Parts Discussed in Thread: BQ29330 , BQ20Z65 Hi,
The typical application of bq29330 has RC filter on each VCx pins and capacitors connected between VCx pin and GND. Now our customer plan to configure RC filter like the picture on right-hand side…
Wait, that means that there I cant just turn ballancing on via I2C and let it work, I have to check the voltages via microcontroler and via same microcnotroler send instructions to e.g. open bypass fet on cell 3? if that is so it is not big deal but it…
Other Parts Discussed in Thread: BQ29330 Hi, dear all,
I am using bq29330 for battery management, does bq29330 can detect when PACK pin connected to charger, and then control which CHG and DSG FETs close or open to enter charging mode?
Or it must…
