BQ24008PWP Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a compact layout with the IC placed close to the battery and the input capacitors. The layout should also minimize the loop area of the power paths to reduce EMI. A recommended layout is shown in the TI application note SLUA433.
  • The selection of external components such as the input capacitor, output capacitor, and inductor depends on the specific application requirements. TI provides a component selection guide in the datasheet and application notes. Additionally, the TI Webench tool can be used to select the optimal components for a specific design.
  • The BQ24008PWP can handle input voltages up to 18V, but it is recommended to limit the input voltage to 12V to ensure reliable operation and to prevent damage to the IC.
  • The charge current and voltage can be configured using external resistors connected to the ISET and VREG pins. The datasheet provides a detailed explanation of how to calculate the required resistor values for a specific charge current and voltage.
  • The EN pin is an enable input that allows the user to turn the charger on or off. When the EN pin is low, the charger is disabled and the output is disconnected from the input. This pin can be used to implement a power-saving mode or to disable the charger during shipping or storage.
