I cannot express how frustrating and annoying this is. We have spent countless hours working with TI support trying to address our application and now, after being sent off on a wild goose chase adjusting hardware protection etc., we find…
Part Number: BQ34Z100 Tool/software: Gauge team,
Our customer is working with BQ34Z100 in a battery pack. The fuel gauge pulls the clock line low indefinitely and the only way to get it to release is a power cycle of the gauge.
The clock is running…
Hi MJ, Recommendations are: 1- BQ27z561-R2 2- BQ27z746 Out of curiosity, often ESS systems require higher cell count configuration from what I have heard. What type of energy storage system is this? Regards, Jose Couso
Hello Akilarasan,
The TRM contains the details about the PULS pin operation: 7.1 Description
You can review the TRM for information regarding the interrupts the BQ27Z561 can provide, there are multiple different configurations available.
The device…
Hi,
Yes, this should have the same effect.
I recommend an Impedance Track gauge for your application, I believe you are trying to gauge a 1s LFP battery. These are my recommendations for that application. I recommend using the GPCCHEM tool and discharging…
Hi Akilarasan, Correct, ROM gauges come with pre-defined ChemID stated in datasheet. You have two options:
1- Obtain the same cell chemistry defined as chemID = 1202 in my previous reply. 2- Purchase a flash gauge. Flash gauges allows you to program…
Hey Josh,
You can force the gauge to open up the R2 version of the firmware by selecting "1561_2_01-bq27z561R2.bqz", from there you can go on the product page for the BQ27z561-R2 and download the firmware and then program the -R2 srec file onto the…
Part Number: BQ27421-G1 Other Parts Discussed in Thread: BQ27Z561-R2 Dear Team,
We’re looking for a fuel gauge IC for the next generation BT Audio SoC evaluation. Do you know if the BQ27421-G1 is already in MP phase? Or other TI suggestions?
Many…
