BQ25892RTWR Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow the guidelines in the TI application note 'AN-1149: PCB Layout Guidelines for Switching Regulators'. Additionally, it's essential to minimize the loop area of the power traces and keep the input and output capacitors close to the IC.
  • The selection of the inductor depends on the specific application requirements. TI recommends using an inductor with a low DC resistance (DCR) and a high saturation current rating. The inductor value should be chosen based on the output voltage, output current, and switching frequency. TI provides an inductor selection guide in the datasheet, and online tools like the TI Inductor Selection Tool can also be used.
  • The BQ25892RTWR is rated for operation from -40°C to 125°C. However, the maximum ambient temperature range may be limited by the specific application and the thermal design of the system. It's essential to ensure that the IC is operated within its recommended operating conditions to ensure reliability and performance.
  • The BQ25892RTWR has a built-in overcurrent protection feature that can be enabled by connecting the OCSET pin to a resistor divider network. The resistor values should be chosen based on the desired overcurrent threshold. TI provides a detailed explanation of the overcurrent protection feature in the datasheet.
  • TI recommends using a low-ESR ceramic capacitor with a value of 10uF to 22uF for the input capacitor. The capacitor should be placed close to the VIN pin and have a voltage rating that exceeds the maximum input voltage.
