DRV104PWPRG4 datasheet by Texas Instruments

DRV104PWPRG4 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for DRV104PWPRG4 to ensure optimal performance?
  Texas Instruments provides a recommended PCB layout in the DRV104PWPRG4 evaluation module's user guide, which includes guidelines for component placement, trace routing, and thermal vias to ensure optimal performance and thermal management.
• How do I implement overcurrent protection with DRV104PWPRG4?
  The DRV104PWPRG4 has a built-in overcurrent protection feature. To implement it, connect a sense resistor (Rs) between the output pins (VOUT) and the GND pin. The overcurrent threshold is set by the value of Rs. The device will shut down if the current exceeds the set threshold.
• Can I use DRV104PWPRG4 in a high-temperature environment?
  Yes, the DRV104PWPRG4 is rated for operation up to 125°C. However, the device's power rating and efficiency will degrade at higher temperatures. Ensure proper thermal management, such as heatsinking and airflow, to maintain optimal performance.
• How do I configure the undervoltage lockout (UVLO) feature in DRV104PWPRG4?
  The UVLO feature is enabled by default. To configure it, connect a resistor divider network between the VIN pin and the GND pin to set the desired undervoltage threshold. Refer to the datasheet for the recommended resistor values and calculation.
• What is the minimum input voltage required for DRV104PWPRG4 to operate?
  The DRV104PWPRG4 requires a minimum input voltage of 7V to operate. However, the recommended input voltage range is 8V to 42V for optimal performance and efficiency.
