Overview
The DRV8353FSRTAR is a highly-integrated gate driver from Texas Instruments, designed for three-phase brushless DC (BLDC) motor applications. This device is part of the DRV835x family, which includes features such as field-oriented control (FOC), sinusoidal current control, and trapezoidal current control of BLDC motors. The DRV8353FSRTAR utilizes smart gate drive (SGD) architecture to minimize the number of external components required for MOSFET slew rate control and protection circuits, optimizing dead time to prevent shoot-through conditions and reducing electromagnetic interference (EMI).
