  • [FAQ] BQ25750: What do I need to know about the BQ25750 power path switchover?

    Part Number: BQ25750 Tool/software: By default, the BQ25750 has an automatic power path switchover. When the VAC power is out the of range set by the ACUV/ACOV resistors, system power will change to VBAT. When VAC is in range again, system power will…

  • [FAQ] What is split output and how to use it?

    TI's gate drivers use a pull-up and pull-down structure in the output stage in order to drive a power device. The pull-up structure supplies the source current to turn on the power device, and the pull-down structure supplies the sink current to turn…

  • [FAQ] BQ40Z50: How to do a two-word override MAC sequence ???

    Tool/software: I am trying to override the Temperature by sending ManufacturerAccess() 0x3008 WriteTemp, but it does not work. What am I doing wrong?

  • [FAQ] What happens when output overshoot or undershoot occurs and how to address it?

    TI's gate drivers use a pull-up and pull-down structure in order to drive the output stage. The pull-up structure supplies the source current to turn on the power device, and the pull-down structure supplies the sink current to turn off the power device…
