BQ24159YFFR Frequently Asked Questions (FAQs)

  • The maximum input voltage is 18V, but it's recommended to keep it below 15V to ensure reliable operation and prevent overheating.
  • The charge voltage and current limits can be configured using external resistors connected to the VSET and ISET pins. Refer to the datasheet for the calculation formulas and examples.
  • The EN (Enable) pin is used to enable or disable the charger. When EN is high, the charger is enabled, and when EN is low, the charger is disabled. This pin can be used to control the charger's power state or to implement a power-saving feature.
  • The BQ24159YFFR has a built-in battery detection feature that can detect battery insertion and removal. When a battery is inserted, the charger starts charging, and when the battery is removed, the charger stops charging and enters a low-power state.
  • The TS (Thermal Sense) pin is used to monitor the charger's temperature. When the temperature exceeds a certain threshold, the TS pin goes low, indicating an over-temperature condition. This pin can be used to implement thermal protection or to monitor the charger's temperature.
