The DRV8378-Q1 provides a single-chip integrated FET
power stage for driving brushless-DC motors. The DRV8378-Q1 integrates three 1/2H
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-Q1 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-Q1 is capable of driving a PWM frequency up to 200kHz.
