DRV5023AJEDBZTQ1 datasheet by Texas Instruments

DRV5023AJEDBZTQ1 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for DRV5023AJEDBZTQ1 to minimize EMI?
  Texas Instruments provides a recommended PCB layout in the DRV5023 application note (SLVAUH5) that includes guidelines for component placement, routing, and shielding to minimize EMI.
• How do I choose the right sense resistor value for my application?
  The sense resistor value depends on the motor current and the desired current sense accuracy. A general guideline is to choose a sense resistor value that results in a voltage drop of 50-100 mV at the maximum motor current. TI provides a sense resistor calculator tool to help with the selection.
• What is the maximum operating temperature range for DRV5023AJEDBZTQ1?
  The DRV5023AJEDBZTQ1 has an operating temperature range of -40°C to 125°C, but the maximum junction temperature (TJ) should not exceed 150°C. It's essential to ensure proper thermal design and heat sinking to maintain a safe operating temperature.
• Can I use DRV5023AJEDBZTQ1 with a brushed DC motor?
  Yes, the DRV5023AJEDBZTQ1 is suitable for brushed DC motor applications. However, it's essential to ensure that the motor's back-EMF does not exceed the device's maximum voltage rating. Additionally, the device's overcurrent protection and undervoltage lockout features should be configured according to the motor's requirements.
• How do I implement overcurrent protection with DRV5023AJEDBZTQ1?
  The DRV5023AJEDBZTQ1 has a built-in overcurrent protection feature that can be configured using the OCx pins. The device can be set to latch off or auto-retry in case of an overcurrent event. The overcurrent threshold can be adjusted using an external resistor divider network.
