Description

The DRV835x family of devices are highly-integrated gate drivers for three-phase brushless DC (BLDC) motor applications. These applications include field-oriented control (FOC), sinusoidal current control, and trapezoidal current control of BLDC motors. The device variants provide optional integrated current shunt amplifiers to support different motor control schemes and a buck regulator to power the gate driver or external controller.The DRV835x uses smart gate drive (SGD) architecture to decrease the number of external components that are typically necessary for MOSFET slew rate control and protection circuits. The SGD architecture also optimizes dead time to prevent shoot-through conditions, provides flexibility in decreasing electromagnetic interference (EMI) by MOSFET slew rate control, and protects against gate short circuit conditions through VGS monitors. A strong gate pulldown circuit helps prevent unwanted dV/dt parasitic gate turn on eventsVarious PWM control modes (6x, 3x, 1x, and independent) are supported for simple interfacing to the external controller. These modes can decrease the number of outputs required of the controller for the motor driver PWM control signals. This family of devices also includes 1x PWM mode for simple sensored trapezoidal control of a BLDC motor by using an internal block commutation table.

Features

  • Three-phase inverter with 24-60VDC input and 10 Arms continuous phase current for servo drives
  • Very high peak efficiency (99.0%) eliminates need for heat sink or cooling fan
  • Smart three phase gate driver DRV8350R with on-chip hardware protection and integrated DC/DC buck for gate drive supply
  • Fully protected power stage: Shoot-through, over current, short circuit, under voltage, over temperature protection
  • Programmable gate driver source/sink currents from 50mA to 2A eases optimization of efficiency and EMI performance including VGS handshake and minimum dead-time insertion to avoid shoot-through
  • In-phase shunt measurement based (1mOhm) current sensing with INA240 high-common mode rejection zero-drift current sense amplifier

Typical applications

  • Servo CNC and Robotics / Industrial Robots / AC Inverter and VF Drives
