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.
