DRV8353RSRGZR

All devices in the DRV835x series are highly integrated gate drivers suitable for three-phase brushless DC (BLDC) motor application standards. These applications include field-oriented control (FOC), sinusoidal current control, and trapezoidal current control of BLDC motors. The device models offer optional integrated shunt amplifiers to support different motor control schemes and also provide a buck regulator to power the gate driver or external controller. The DRV835x reduces the number of external components typically required for MOSFET slew rate control and protection circuits by adopting an intelligent gate drive (SGD) architecture. The SGD architecture can also optimize the dead time to prevent shoot-through issues, offers flexibility in reducing electromagnetic interference (EMI) through MOSFET slew rate control technology, and can prevent gate short-circuit problems through the VGS monitor. A powerful gate pull-down circuit helps prevent unnecessary dV/dt parasitic gate turn-on events. This series of devices supports various PWM control modes (6x, 3x, 1x, and independent modes), which simplifies the connection with external controllers. These modes can reduce the number of controller outputs required for the motor driver PWM control signals. This series of devices also includes the 1x PWM mode, enabling easy sensor-based trapezoidal control of BLDC motors through an internal block commutation table.
