DRV8317 provides three integrated MOSFET half-bridges for driving three-phase brushless DC (BLDC) motors with 5-V, 9-V, 12-V, or 18-V DC rails or 2s to 4s batteries. The device provides integrated three-phase current sensing which eliminates the need for external sense resistors. DRV8317 has an integrated LDO that provides a regulated 3.3-V rail capable of delivering up to 80mA for external loads like MCU, logic circuits, hall sensors etc.,

DRV8317 provides a configurable 6x or 3x PWM control scheme which can be used to implement sensored or sensorless field-oriented control (FOC), sinusoidal control, or trapezoidal control using an external microcontroller. DRV8317 is capable of driving a PWM frequency of up to 200 kHz. DRV8317 is highly configurable either through SPI (DRV8317S) or pins (DRV8317H) - PWM mode, slew rate, current sense gain are some of the configurable features.

A number of protection features including supply under voltage lockout (UVLO), over voltage protection (OVP), charge pump under voltage (CPUV), over current protection (OCP), over temperature warning (OTW) and over temperature shutdown (OTS) are integrated into DRV8317 to protect the device, motor, and system against fault events. Fault conditions are indicated by the nFAULT pin.
