DRV8886ATRHRT Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the DRV8886ATRHRT evaluation module (EVM) user's guide, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize EMI.
  • The sense resistors (RSENSE) should be chosen based on the motor current and the desired current sense accuracy. A lower sense resistor value provides better current sense accuracy but increases power loss. TI provides a sense resistor selection guide in the datasheet and application notes.
  • The DRV8886ATRHRT has an operating temperature range of -40°C to 125°C, but the maximum junction temperature (TJ) should not exceed 150°C. The device should be derated for operation above 85°C to ensure reliability and prevent thermal shutdown.
  • The DRV8886ATRHRT has a built-in overcurrent protection (OCP) feature that can be enabled by connecting the OCP pin to a resistor divider network. The OCP threshold can be set by adjusting the resistor values. TI provides an application note with detailed guidelines for implementing OCP.
  • The DRV8886ATRHRT is designed for three-phase brushless DC (BLDC) motors, but it can be used with a brushed DC motor with some modifications. However, the device's built-in commutation logic and hall sensor inputs would not be utilized. TI provides an application note with guidelines for using the DRV8886ATRHRT with a brushed DC motor.
