DRV5021A2QDBZR Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the DRV5021A2QDBZR evaluation module (EVM) user's guide, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize noise.
  • The sense resistor value depends on the desired current sensing range and the output voltage of the DRV5021A2QDBZR. A general guideline is to choose a sense resistor value that results in a voltage drop of 50-100 mV at the maximum expected current. TI provides a sense resistor calculator tool to help with this selection.
  • Although the datasheet specifies a recommended operating voltage range of 3.3 V to 5.5 V, the absolute maximum rating for the VCC pin is 6.5 V. However, it's essential to ensure that the voltage on the VCC pin does not exceed the recommended operating range to prevent damage to the device.
  • The DRV5021A2QDBZR is rated for operation up to 125°C, but the device's performance and accuracy may degrade at higher temperatures. It's crucial to consider the device's thermal management and ensure that the junction temperature (TJ) does not exceed the recommended maximum rating.
  • To filter out noise and aliasing, a low-pass filter can be added to the current sense output. The filter's cutoff frequency should be set based on the desired bandwidth and noise tolerance. Additionally, proper PCB layout and shielding can help minimize noise coupling and aliasing.
