Description for the DRV8353R

The DRV835x family of devices are highly-integrated gate drivers for three-phasebrushless DC (BLDC) motor applications. These applications include field-oriented control (FOC),sinusoidal current control, and trapezoidal current control of BLDC motors. The device variantsprovide optional integrated current shunt amplifiers to support different motor control schemes anda buck regulator to power the gate driver or external controller.

The DRV835x uses smart gate drive (SGD) architecture to decrease the number of externalcomponents that are typically necessary for MOSFET slew rate control and protection circuits. TheSGD architecture also optimizes dead time to prevent shoot-through conditions, provides flexibilityin decreasing electromagnetic interference (EMI) by MOSFET slew rate control, and protects againstgate short circuit conditions through VGS monitors. A strong gate pulldowncircuit helps prevent unwanted dV/dt parasitic gate turn on events

Various PWM control modes (6x, 3x, 1x, and independent) are supported for simpleinterfacing to the external controller. These modes can decrease the number of outputs required ofthe controller for the motor driver PWM control signals. This family of devices also includes 1xPWM mode for simple sensored trapezoidal control of a BLDC motor by using an internal blockcommutation table.
