Maybe the BQ29312 is dead, the BQ29312A have an internal regulator pin 18. If the fuse have burn something is (was wrong). Maybe you connected the new battery inverter. You can check the Pin 1 of the BQ29312 the voltage must be battery.
Other Parts Discussed in Thread: BQ20Z80 , BQ29312 Hi,
I am using the bq20z80 and bq29312 for an project.
By reading documentations I did not found this information:
Is the Dicharge FET is turned off when the circuit going in sleep with NR=1 ?
Thanks…
Other Parts Discussed in Thread: BQ29312 , BQ2060A Does anybody have any experience in using the bq2084 and bq29312 devices for control of NiMH battery packs? Can this be done in a meaningful fashion?
Any response would be greatly appreciated.
Thanks…
Other Parts Discussed in Thread: BQ20Z80 Hi, I did not found for BQ20Z80 the execution time for Voltage update, during SLEEP Mode. (SLUA380 Page 95) This information could be interesting in order to determine the average current versus the "Sleep Current…
Other Parts Discussed in Thread: BQ29312 We run a product with bq29312, we suspect that something is wrong with the BQ29312, I detect a diode between VC4 (pin 6) and VC5(pin 7) a read a diode, when I use a fluke 110 position diode measure, positive terminal…
Part Number: BQ40Z50-R2 Other Parts Discussed in Thread: BQ29312 , BQ20Z80 , , BQ40Z50 Hi TI Team,
I'm using bq40z50-r2 to replace bq20z80+bq29312. In dataflash, I found in 20z80+29312, there is a NCSMB bit in Operation Cfg B. I'm wondering if in 40z50…
Also can you get me some more information about the BQ77915 internal MOSFETs. The data is scattered and seems to be inconsistent.
For example the BQ77915 says it is 12ohms typical at 4V.
The BQ29312/330 seems be be 330ohm at 2.24V, 260ohm at 2.6V and…
Part Number: BQ40Z50-R2 Other Parts Discussed in Thread: BQ29312 , BQ20Z80 , , BQ40Z50 Hello TI Team,
I'm working on a design using BQ40Z50-R2 to replace BQ20Z80+BQ29312 chip set. When I look up the datasheet for SMBus rise and fall time, I found the test…
Other Parts Discussed in Thread: BQ2083 , BQ29312 Trying to find a datasheet for the IC bq20862dbt. That is a gas gauge IC, designed; - I imagine, to work with the bq29312 AFE protection IC, something like the bq2084. I read it is a DQ Bus version of the…
Hi Mohsen,
BQ2084 is an old device that was released before BQStudio. The link to the software for this device is here: www.ti.com/.../ev2300-084
This device is also showing as NRND (not recommended for new designs). It is designed to work with the BQ29312…
