The DRV8304 device is an integrated gate driver for 3-phase brushless DC BLDC motors applications for 12V and 24V DC rails. These applications include field-oriented control FOC, sinusoidal current control, and trapezoidal current control of BLDC motors. The device integrates three current-sense amplifiers CSA for sensing the phase currents of BLDC motors for optimum FOC and current-control system implementation. An AUTOCAL feature automatically calibrates the CSA offset error for accurate current sensing.
