  • [FAQ] TDA4VM: SDK8.02/8.01: Keywriter build failure

    Part Number: TDA4VM On the SDK 8.02 the keywriter build fails with the below error: Compiling j721e_evm:j721e:mcu1_0:release:keywriter_img: /nhome/sdk/ti-processor-sdk-rtos-j721e-evm-08_01_00_13/pdk_jacinto_08_01_00_36/packages/ti/boot/keywriter/init…

  • [FAQ] How long does the voltage on the PACK pin need to be applied to wake-up the gauge?

    To wake-up the gauge from shutdown, a voltage above the VSTARTUP needs to be applied to the PACK pin for a minimum time of 30ms to wake-up the hardware. After the hardware is awake it can take up to 2 seconds for the firmware to initialize and calculate…

  • [FAQ] How to enter UNSEAL or FULL ACCESS modes after sealing the gauge?

    TI battery gauges use the security modes SEAL/UNSEAL/FULL ACCESS in order to help protect the flash memory of the gauge from third parties reading the gauge’s configuration memory. This prevents any copying of the gauge or BMS system. The mode information…

  • [FAQ] Why does Valid Charge Termination (VCT) take less or more than 80 seconds to trigger?

    Impedance Track battery gauges use VCT to help determine the full charge of a battery. VCT is used to help determine the range we report for Relative State of Charge (RSoC). The gauge will learn the Depth of Discharge at End of Charge (DoD at EoC) when…
