BQ25071DQCR Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general guidelines for switching regulator layouts, such as keeping the input and output capacitors close to the IC, and using a solid ground plane to reduce noise and EMI.
  • The datasheet provides a list of recommended inductors, but you can also use the following guidelines: choose an inductor with a high saturation current, low DC resistance, and a suitable inductance value based on the switching frequency and output current requirements.
  • The datasheet specifies a maximum input voltage of 18V, but it's recommended to derate this value based on the specific application and operating conditions to ensure reliable operation.
  • The BQ25071DQCR has a built-in OVP feature that can be enabled by connecting the OVP pin to a voltage divider network that sets the OVP threshold. The datasheet provides more details on how to implement OVP.
  • The thermal derating curve is not explicitly provided in the datasheet, but it can be obtained from Texas Instruments' application notes or by contacting their technical support. The curve provides information on how to derate the device's performance based on the operating temperature.
