BQ24750RHDT 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 application note 'BQ24750RHDT Layout Guidelines' (SLUAUH7) for optimal performance and thermal management.
  • The selection of external components such as inductors, capacitors, and resistors depends on the specific application requirements. Texas Instruments provides a component selection guide in the datasheet, but it's also recommended to use the WEBENCH Power Designer tool to simplify the component selection process.
  • The maximum ambient temperature for the BQ24750RHDT is 85°C, but it's recommended to derate the device's performance at higher temperatures to ensure reliable operation. Refer to the thermal derating curves in the datasheet for more information.
  • The BQ24750RHDT has a built-in overcurrent protection feature that can be enabled by connecting the OCP pin to a resistor divider network. The resistor values can be calculated using the equations provided in the datasheet. Additionally, the device also has a programmable overcurrent threshold using the I2C interface.
  • The BQ24750RHDT is rated for a maximum input voltage of 24V, but it can be used in high-voltage applications with the use of an external voltage regulator or a DC-DC converter to step down the input voltage. However, it's essential to ensure that the device's absolute maximum ratings are not exceeded.
