DRV8311 Datasheet Three-phase Pwm Motor Driver

Manufacturer: Texas Instruments

Overview: DRV8311 SLVSFN2B – SEPTEMBER 2021 – REVISED FEBRUARY 2022 DRV8311 Three-Phase PWM Motor Driver.

General Description

The DRV8311 provides three integrated MOSFET half-H-bridges for driving a three-phase brushless DC (BLDC) motor for 5-V, 9-V, 12-V, or 18-V DC rails or 1S to 4S battery powered applications.

The device integrates three current-sense amplifiers (CSA) with integrated current sense for sensing the three phase currents of BLDC motors to achieve optimum FOC and current-control system implementation.

The DRV8311P device provides capability to generate and configure PWM timers over Texas Instruments SPI (tSPI), and allows the control of multiple
