BQ25792RQMR Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the datasheet, but it's essential to follow good PCB design practices, such as keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing trace lengths and widths to reduce EMI.
  • The BQ25792RQMR has a programmable charging profile, and the optimal profile depends on the specific battery chemistry. Consult the battery manufacturer's recommendations and adjust the charging profile accordingly. You can also use TI's battery management software to customize the charging profile.
  • The BQ25792RQMR is rated for operation from -40°C to 85°C. However, the device's performance and reliability may degrade at extreme temperatures. Ensure proper thermal design and heat dissipation to maintain optimal performance.
  • The BQ25792RQMR has built-in OVP and UVP features. For OVP, the device will automatically disconnect the input when the voltage exceeds the OVP threshold. For UVP, the device will enter a low-power state when the input voltage falls below the UVP threshold. You can adjust these thresholds using external resistors.
  • The BQ25792RQMR is designed for input voltages between 3.5V and 24V. While it's possible to use it with non-standard input voltages, this may require custom configuration and may affect the device's performance and reliability. Consult TI's application notes and technical support for guidance.
