BQ24298RTWR Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output capacitors close to the IC, and use short, wide traces for the power paths. Refer to the TI application note 'BQ24298RTWR PCB Layout Guidelines' for more details.
  • Choose input capacitors with a voltage rating of at least 1.5 times the maximum input voltage, and output capacitors with a voltage rating of at least 1.5 times the output voltage. Select capacitors with low ESR (Equivalent Series Resistance) and a capacitance value of at least 10uF for the input and 22uF for the output.
  • The BQ24298RTWR is rated for operation from -40°C to 85°C. However, the device can be operated at temperatures above 85°C with derating, but this may affect its reliability and lifespan.
  • Use the I2C interface to configure the charging profile, including the charge voltage, charge current, and termination current. Refer to the datasheet and the TI application note 'BQ24298RTWR Programming Guide' for more details.
  • The EN (Enable) pin is used to enable or disable the charging function. Tie the EN pin to a logic high (VCC) to enable charging, or tie it to a logic low (GND) to disable charging. You can also use the EN pin to implement a power button or a charging enable signal.
