DRV8317 3-Phase PWM Motor Driver

Texas Instruments' integrated MOSFET driver is suitable for driving 3-phase motors

Image of Texas Instruments' DRV8317 3-Phase PWM Motor DriverTexas Instruments' DRV8317 3-phase PWM motor driver provides three integrated MOSFET half-bridges for driving 3-phase brushless DC (BLDC) motors with 5 V, 9 V, 12 V, or 18 V DC rails or 2s to 4s batteries. The driver provides integrated 3-phase current sensing, eliminating the need for external sense resistors. The DRV8317 has an integrated LDO that provides a regulated 3.3 V rail that can deliver up to 80 mA for external loads such as microcontrollers (MCUs), logic circuits, hall sensors, and more. The configurable 6x or 3x PWM-control scheme can implement a sensored or sensorless field-oriented control (FOC), sinusoidal control, or trapezoidal control using an external MCU.

The DRV8317 can drive a PWM frequency of up to 200 kHz and is highly configurable through the SPI (DRV8317S) or pins (DRV8317H). The configurable features include PWM mode, slew rate, current-sense gain, and more. The integrated protection features include supply undervoltage lockout (UVLO), overvoltage protection (OVP), charge-pump undervoltage (CPUV), overcurrent protection (OCP), overtemperature warning (OTW), overtemperature shutdown (OTS), and protects the device, motor, and the system against fault events which are indicated by the nFAULT pin.
