TI’s DRV10x family of motor drivers includes gate drivers, integrated MOSFET, and integrated control functionality to spin a motor without an external microcontroller. DRV10x devices minimize noise and vibration with true and accurate 180° sinusoidal algorithms. Our motor drivers feature trap, sine, and FOC control variants for optimal efficiency in a variety of motors. Sensorless algorithms further reduce design complexity by removing Hall sensors.

The DRV10x family provides simple control of motor speed by applying a PWM input to control the magnitude of the drive voltage. This is accomplished by driving the PWM pin with an analog voltage or writing the speed command directly through the I²C port and monitoring the FG pin for speed feedback. An adjustable lead angle feature in DRV10x devices allows the user to optimize the driver efficiency by aligning the phase current and the phase Back-EMF. Lead angle adjustment achieves the best efficiency regardless of the motor parameters and load conditions. DRV10x devices deliver current to the motor with an input supply voltage ranging from 2.1-V to 30-V. In some devices, if the power supply voltage is higher than the maximum voltage threshold, the device stops driving the motor and protects the device circuitry. DRV10x devices feature an integrated step-down regulator to accurately step down the supply voltage to either 5-V or 3.3-V for powering both internal and external circuits. Devices are available in either a sleep mode or a standby mode version to conserve power when the motor is not running.
