BQ24296MRGET Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate layer for the power traces is recommended. Keep the input and output capacitors close to the IC and use short, wide traces for the power paths.
  • Choose an inductor with a high saturation current rating, low DCR, and a high SRF. A 10uH to 22uH inductor with a saturation current rating of 2A to 3A is a good starting point.
  • A low-ESR ceramic capacitor (X5R or X7R) with a value of 4.7uF to 10uF is recommended. This helps to filter the input voltage and reduce ripple.
  • The BQ24296MRGET has a programmable charge voltage and current limit. Use the I2C interface to configure the charger for different battery chemistries, such as Li-ion, LiFePO4, or NiMH.
  • The BQ24296MRGET is rated for operation up to 85°C ambient temperature. However, the charger's efficiency and reliability may degrade at high temperatures, so it's recommended to keep the ambient temperature below 70°C for optimal performance.
