The DRV7308 is a three-phase intelligent power module (IPM) that consists of 205mΩ, 650V e-mode Gallium-Nitride (GaN) for driving three-phase BLDC/PMSM motors up to 450V DC rails. The applications include field-oriented control (FOC), sinusoidal current control, and trapezoidal (six step) current control of BLDC motors. The device helps to achieve more than 99% efficiency for a 3-phase modulated, FOC-driven, 250W motor drive application in a QFN 12mm x 12mm package at 20kHz switching frequency, eliminating the need for heat sink. The device helps to achieve ultra quiet operation, with very low dead time. The integrated bootstrap rectifier with bootstrap current limit, eliminates the need for an external bootstrap diode.
