Other Parts Discussed in Thread: BQ27500-V130 , BQ27500 I have a BQ27500-V130 Fuel Gauge in my design.
The BATT-LOW signal is connected to a MSP430 (GPI). This signal does not toggle when the battery capacity goes below the set threshold.
I have…
Other Parts Discussed in Thread: BQ27500-V130 Hello - I'm hoping you may be able to shed some light on a difficulty I'm having with the bq27500-v130 in my production boards, and also answer a question about my implementation.
1. The gauge is over-estimating…
Other Parts Discussed in Thread: BQ27500-V130 , BQ27510-G3 , BQ27500 Hi there,
I haven't used a fuel gauge IC before and I was hoping someone could just check that I am not misleading myself - I plan to purchase the EVM to de-risk.
I am looking at…
Other Parts Discussed in Thread: BQ24075 , BQ27500 Hi,
I have a platform that uses bq24075 to charge the battery, and uses the bq27500 for battery gauging,
here is my experiment data for reading the AverageCurrent() form bq27500:

Charles,
Let me continue for Jay....... We program the BQ27500 device using the Evaluation Software, going into Data Flash, importing a .gg file, and then using Write_All / Preserve. We do not seal the chip.
On the chips that do not work after programming…
Other Parts Discussed in Thread: BQ27500 Hello,
I'm trying to write .bqfs file to BQ27500 gauge. It seems that I can read values in ROM mode. Unfortunately writing is blowing up all over the place. So I manually did all the startup writes and they seemed…

Other Parts Discussed in Thread: BQ27500 Hello-
We are having an issue with the BQ27500 after environmental testing, which includes shipping temperature extremes and moving quickly between them. The test goes from -20 to +60 degrees C. After the test…
Other Parts Discussed in Thread: BQ27500-V130 , BQ24610 I am using a Bq27500-V130 in a multi-cell (2S) configuration with a Bq24610 charger. The operations configuration register has the RMFCC bit set by default. When the battery is fully charged, FCC…
Anyone,
we are using TI's EVM board for both charger and monitor. The battery pack thermistor is directly connected to the gas gauge and is reading correctly (22degC). We verify that the voltage and current are all calibrated so that the gas gauge…
