The DRV8378 provides a single-chip integrated FET power stage for driving brushless-DC motors. The DRV8378 integrates three 1/2-H bridges with 70V absolute maximum capability and a very low RDS(ON) of 58mΩ (high-side plus low-side) to enable high power drive capability. Current is sensed using an integrated current sensing feature which eliminates the need for external sense resistors. An integrated LDO generate the necessary voltage rails for the device and can be used to power external circuits. Each output driver channel consists of N-channel power MOSFETs configured in a half-bridge configuration.
DRV8378 implements a 6x or 3x PWM control scheme which can be used to implement sensored or sensorless field-oriented control (FOC), sinusoidal control, or trapezoid control using an external microcontroller. The DRV8378 is capable of driving a PWM frequency up to 200kHz.
