A good PCB layout for the DRV2700RGPT involves keeping the high-current paths short and wide, using a solid ground plane, and placing the device close to the motor. TI provides a recommended PCB layout in the datasheet and application notes.
The sense resistor value depends on the motor current and the desired current sense accuracy. A good starting point is to use the formula Rsense = 0.05 / Imax, where Imax is the maximum motor current. TI provides a sense resistor calculator tool to help with the selection.
The internal bootstrap diode is used to generate the high-side gate drive voltage. It eliminates the need for an external bootstrap diode and reduces the component count. However, it also means that the high-side gate drive voltage is limited to VCC + 0.6V, which may affect the design of the power stage.
The DRV2700RGPT has built-in overcurrent protection (OCP) and overtemperature protection (OTP). However, additional protection measures can be taken, such as using external current sense resistors, thermal sensors, and fuses. It's also important to follow proper thermal design and PCB layout practices to prevent overheating.
No, the DRV2700RGPT is designed for brushed DC motors only. It does not have the necessary commutation logic and control signals for brushless DC motors. TI offers other devices, such as the DRV8301, that are specifically designed for brushless DC motor control.
