BQ24070RHLTG4 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 rating, low DC resistance, and a suitable inductance value based on the switching frequency and output current requirements.
  • The BQ24070RHLTG4 has a maximum ambient temperature rating of 85°C, but it's recommended to derate the device's performance at higher temperatures to ensure reliable operation.
  • Yes, the BQ24070RHLTG4 is designed for battery-powered applications and has a low quiescent current (Iq) of 20 μA, making it suitable for battery life extension.
  • The BQ24070RHLTG4 has a built-in OVP feature that can be enabled by connecting the OVP pin to a voltage divider network. The datasheet provides more information on how to implement OVP.
