The DRV8376-Q1 provides a gate drive and power stage for driving a 4.5V to 65V brushless-DC motors. The DRV8376 integrates three 1/2-H bridges with 70V absolute maximum capability and a very low RDS(ON) of 400mΩ (high-side plus low-side) to enable high-power drive capability. Current is sensed using an integrated current sensing feature eliminating the need for external sense resistors. Power management features with integrated LDO generate the necessary voltage rails for the device and can be used to power external circuits.

DRV8376-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 DRV8376 is capable of driving a PWM frequency up to 100kHz. The control scheme is highly configurable through hardware pins or register settings ranging from motor current limiting behavior to fault response.

There are a large number of protection features integrated into DRV8376-Q1, intended to protect the device, motor, and system against fault events.
