DRV8353SMRTAT Frequently Asked Questions (FAQs)
Texas Instruments provides a recommended PCB layout in the DRV8353SMRTAT evaluation module (EVM) user's guide, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize electromagnetic interference (EMI).
The sense resistors (Rs) should be selected based on the motor current and the desired current sense accuracy. A lower sense resistor value provides better current sense accuracy but increases the power loss in the resistor. Texas Instruments recommends using a sense resistor value between 10 mΩ and 100 mΩ, and provides a calculation formula in the datasheet to determine the optimal value.
The DRV8353SMRTAT has an operating temperature range of -40°C to 125°C, but the maximum junction temperature (TJ) should not exceed 150°C. Engineers should ensure that the device is properly cooled and that the thermal management system is designed to keep the junction temperature within the specified range.
The DRV8353SMRTAT is a highly configurable device that can be used with various motor types and topologies. Texas Instruments provides application notes and design guides that provide configuration guidelines for different motor types, such as brushed DC, stepper, and brushless DC motors, as well as different topologies, such as half-bridge and three-phase configurations.
To ensure EMI and EMC compliance, engineers should follow proper PCB layout and design guidelines, use shielding and filtering components, and implement proper grounding and decoupling techniques. Texas Instruments provides guidelines and recommendations for EMI and EMC compliance in the datasheet and application notes.
