Texas Instruments provides a recommended PCB layout in the DRV10964FFDSNR 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 motor current and the desired current sense accuracy. A smaller sense resistor value provides higher current sense accuracy but increases the power loss, while a larger value reduces power loss but decreases accuracy. TI provides a sense resistor calculator tool to help with the selection.
The DRV10964FFDSNR 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 management and heat sinking to prevent overheating.
No, the DRV10964FFDSNR is designed for stepper motor control and is not suitable for brushless DC motor control. TI offers other devices, such as the DRV8313, for brushless DC motor control applications.
The DRV10964FFDSNR has a built-in overcurrent protection feature that can be enabled by connecting the OCP pin to a resistor and capacitor network. The device will shut down if the current exceeds the set threshold. TI provides guidelines for designing the OCP circuit in the datasheet and application notes.
