    Hi David, Thanks for the suggestion. Regarding the updating of FCC after insertion, how soon would it be updating? I was doing a test using a 2200 mAh battery pack with additional resistance (5 ohms) added in series to simulate increased impedance of aged battery pack. Just to see if there will...

    Teik Hooi Teoh
    The system is already up and running when the FCC remains at 2200mAh. Anyway, as you have pointed out the resistance might be too large to simulate the realistic change in battery internal impedance. So I have tried with 500mohm instead and the FCC still remains unchanged. Same when using the 1100mAh...

    Hi, Thanks for the suggestion. Here are the steps to the results: 1. Insert fully relaxed battery (single cell, 1100mAh) while system off (<1mA consumption). 2. bq27510-g1 on my system are programmed with golden profile for 2200mAh battery (two 1100mAh cells in parallel) 2. Turn on system...

    Teik Hooi Teoh
    Hi, My application requires prevention of using aged/degraded battery pack (or battery pack with same chemistry but lower capacity). The purpose is to ensure there is enough battery capacity to sustain for whole operation whenever a battery pack is inserted to my system. Example, my system suppose...

    I have written the firmware to program the BQ27510 from the three page flow chart from Going to Production with the bq2750x. However, every time I read register 0x66 to see if the data=0x00 I get the data to equal 0x37. Does anyone have any idea why this might be happening? I'm thinking maybe...

    I found the other post about this but still have questions. I am not using a thermistor and the datasheet doesn't do a good job of explaining the internal circuitry. My circuit is powered from the battery only. From the reference schematic, can I drop the 1.8M, 18.2k, and 1k resistors and tie...

    Hi, In my board all the boards (actually four of them) .... BQ27510 pin REG25 provides an output of 3V instead of 2.5V at the REG25 pin as mentioned in datasheet.....initially i came to the conclusion that this might be because I am applying a REGIN of 11.1V way above the recommended condition......
