BQ24381DSGR Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the datasheet (section 10.1) and in the application note SLUA645. It's essential to follow these guidelines to minimize noise, ensure proper thermal dissipation, and optimize performance.
  • The sense resistor value depends on the maximum current and voltage of your system. TI provides a sense resistor calculation formula in the datasheet (section 7.3.1). You can also use the BQ24381 Evaluation Module (EVM) as a reference design.
  • The EN (enable) pin is used to turn the device on or off. When EN is high, the device is enabled, and when EN is low, the device is disabled. This pin can be used to implement power-saving modes or to reset the device. See the datasheet (section 7.3.2) for more information.
  • The BQ24381 has built-in OVP and UVP features. For OVP, the device will latch off when the input voltage exceeds the OVP threshold (typically 28V). For UVP, the device will latch off when the input voltage falls below the UVP threshold (typically 6V). You can adjust these thresholds using external resistors (see datasheet section 7.3.3).
  • The FAULT pin is an open-drain output that indicates when a fault condition occurs, such as overcurrent, overvoltage, or undervoltage. You can connect this pin to a microcontroller or other logic to take action when a fault is detected. See the datasheet (section 7.3.4) for more information.
