Other Parts Discussed in Thread: BQ27501 Hi,
Thank You for your valuable time and reading the post.
We are using Fuel Gauge Monitor BQ27501 on our HW Platform.
What we have observed is whenever RemainingCapacity shows a value of 150mAh, I see that BAT_LOW…
Other Parts Discussed in Thread: BQ27501 Hi,
I have setup the bq27501 with a single Li-Ion cell with a design capacity of 1220mAh.
When configuring the gas gauge, I entered the design capacity as 1220mAh as I proceeded through the bqEASY wizard. I also…
Other Parts Discussed in Thread: BQ27501 , BQ27510 Hi,
I have implemented a BQ27501 to monitor a multi pack Li-poly battery. Based on SLUA496, an opamp scales down the battery voltage and supplies the BAT pin. The #BAT_GD pin is never pulled to GND,…

We are implementing your bq27501 battery monitor. We are having problems with the RID function... The monitor does not seem to react to the change in RID resistor. Could you please explain when this test is…
Other Parts Discussed in Thread: BQ27501 Hi,
In our HW we are using BQ27501 Battery Mgmt IC. The control interface is I2C.
Now, my question I wanted to know actual I2C Communication between the Processor and BQ27501.
For example I wish to read the current…
Hi,
I have read this document (http://focus.ti.com.cn/cn/lit/an/slua467a/slua467a.pdf) regarding how to structure I2C messages for the gas gauge - but I am looking for a list of all the commands and I am having a hard time locating such a list.
Can…
Other Parts Discussed in Thread: BQ27501 , BQ27500 Hello,
I am using the BQ27501 in a battery powered embedded system where all I have are the PACK+ and PACK- voltages. I have the following questions,
1. Once the initial OCV value is read and the BAT_GD…
Other Parts Discussed in Thread: BQ27501 Hi
I am having problems configuring my bq27501 to use the internal temp sensor. I have left the TS pin floating, however this should not be a problem since I dont intend to use the external sensor.
When I look…
Other Parts Discussed in Thread: BQ27501 Hi
I have come across a strange issue regarding RESET on the BQ27501.
I am using the EVSW connected to pcb which we have designed, containing a bq27501.
I have 2 battery packs with completely diiferent chemisteries…
Sorry for the delay. Yes, you can run the following to get the Chem ID.
1. charge to full and tape with C/100
2. start data logging and log interval is 5 sec
3. relax 2hr
4. discharge with C/10 to terminate volatge
5. relax 5 hr
6. stop data…
