PMIC-Motor drivers, controllers, has been a key application field for motor controllers which is used to control and protect DC motor applications. The DRV8601DRBR is a special type of motor driver which is designed for driving the brush type (DC) motor with automatic turn on and turn off without any use of PWM or logic level signals. The DRV8601DRBR is particularly designed for applications like battery operated or portable electronics, automotive and systems using compact equipment and robotics.

The DRV8601DRBR motor control IC integrates three stages to drive the DC motor with onboard low side MOSFETs and includes power dissipation protection features. It uses a buck topology with external MOSFET and EMI filter with over-voltage protection. All the power driver solutions are integrated within this IC to reduce the necessary external components.

The principle behind the work of the DRV8601DRBR lies in its on-board comparator and PWM controller. The PWM controller along with the input voltage and control signals control the duty-cycle of the PWM wave. This, in turn, triggers the on-board driver IC to provide power to the motor. The output from the driver is then regulated by a FET and EMI filter which provides the regulated current to the motor, thus the motor can operate without any fluctuation of the PWM wave.

Other features of this type of motor controller include variable speed control and protection against under-voltage and reverse battery conditions. The DRV8601DRBR also contains three levels of current sense and thermal management, which provides stability in motor/load operation and protection from any over-current conditions. Additionally, this motor driver has programmable current control and PWM frequency control, allowing the user to select their frequency range which controls and regulates the motor.

Due to its features, the DRV8601DRBR is ideal for applications like industrial robotics, battery powered and portable electronic devices, and any other type of general motion control systems. It offers efficient and safe operation of motors, as well as power and thermal management. The DRV8601DRBR solves the challenging task of providing a highly integrated DC motor control solution with EMI protection, low power dissipation, reliable protection, and low cost.
