  • BQ35100: Can BQ35100 be configured using STM32WLE5CCU6 without BQStudio?

    Part Number: BQ35100 Other Parts Discussed in Thread: BQSTUDIO , EV2400 Hello TI Team, I am using a BQ35100 fuel gauge on a custom PCB with a RAK3172 module (STM32WLE5CCU6) . The BQ35100 is connected to the STM32 through I²C, and the circuit has been…

  • BQ35100: BQ35100 with LiSOCl2 Cell

    Part Number: BQ35100 Hi there, I'm using the BQ35100 on a custom PCB, in conjunction with a SAFT LS14500 (Li-SOCI2) cell (Chem ID: 0623). I have successfully programmed this chemistry to the IC, and I'm trying to read the SOH but have got confusing…

  • BQ35100: BQ35100 and Tadiran TLP-93311/A/SM

    TI Thinks Resolved
    Part Number: BQ35100 Hello, we are using the BQ35100 fuel gauge to get EoS indication for the Tadiran TLP-93311/A/SM battery (Li-SOCl2 plus a hybrid layer capacitor). Would you be able to confirm what the closest Chemistry ID match would be that we…

  • BQ35100: Two BQ35100 on Same I2C Bus — GE Pin as Bus Isolation

    TI Thinks Resolved
    Part Number: BQ35100 Hello TI Support Team, Since the BQ35100 has a fixed I2C address (0x55), we plan to use two devices on the same bus by controlling each GE pin independently from the MCU — only one GE is HIGH at a time. Questions: Is this…

  • BQ35100: BQ35100 suitability for a 4P Li-MnO₂ battery pack and configuration

    Part Number: BQ35100 Other Parts Discussed in Thread: BQSTUDIO , EV2400 Hello, I am evaluating the BQ35100 for a battery-powered system using a primary Li-MnO₂ battery pack composed of four CR34615 cells connected in parallel (nominal voltage 3 V, total…

  • BQ35100: BQ35100 only responds at I2C address 0x0B, no ACK at 0x55, REG25 is 2.5V

    Part Number: BQ35100 Other Parts Discussed in Thread: BQSTUDIO , EV2400 Hi TI Support Team, I am currently testing the BQ35100 in a primary Li-SOCl2 battery monitoring design, but I cannot get the device to respond at the normal I2C address. Test…

  • BQ35100: BQ35100: Steps to profile EVE ER26500 (LiSOCl2) for a 20% EOS alert

    Part Number: BQ35100 Other Parts Discussed in Thread: BQSTUDIO , , EV2400 I am using the BQ35100 in EOS (End of Service) mode to monitor an EVE ER26500 (C-size, 3.6V, 8500mAh) LiSOCl2 battery. I have my board set up and I am using BQStudio with an EV2400…

  • BQ35100: BQ35100 "New Batt R Scale Delay"

    TI Thinks Resolved
    Part Number: BQ35100 I'm testing the functionality of the BQ35100 with SAFT LS14250 (CHEM ID 0x0648). I experience some troubles when "New Batt R Scale Delay" > 0, the EOS is within short time from 100% to 0%, but the battery is not empty. The following…
