PMIC - Motor Drivers, Controllers, have become commonplace in electrical and electronic applications. STK681-320 is a highly reliable and robust motor control device. It is composed of four half-bridge drivers, enabling simultaneous control of 12V to 15A DC Motors. It is used to drive brushless and brushed DC motors, servo motors, micro-step motors and stepper motors.

In terms of features, STK681-320 allows very precise speed control, high efficiency and increased safety due to precise current limiter function. It also supports a flexible input signal such as PWM and linear analog inputs. Additionally, switching frequency of the device is programmable to accommodate a suitable speed requirement with an external resistor.

The two most basic components of a motor are the rotor and the stator (the permanent magnets). The role of the rotor is to carry the energy of the motor. The stator generates an electromagnetic field that pushes and pulls the rotor, resulting in the movement of the motor. Thus, a DC motor generates rotational motion through the action of electrical fields within the stator and the current flow through the rotor.

The STK681-320 is basically responsible for interpreting the signal from the microcontroller to the motor and converting it into a motor speed. The motor driver integrates a constant current limiter, which limits the current used by the motor at a specified level. The constant current limiter is implemented by comparing the sensed current to the reference current. When the sensed current is larger than the reference current, the driver shuts down the power supply and reduces the speed of the motor.

The STK681-320 can be configured to work in many modes. In pulse width modulation (PWM) mode, the duty cycle of the output signal determines the speed of the motor. The duty cycle is determined by the ratio of the motor’s on-time to its off-time period. The STK681-320 has a pulse width modulation option that can be used to achieve the right settings for the motor. In linear analog mode, the control signals sent to the STK681-320 determine the speed of the motor. A linear analog signals consists of a voltage that varies in direct proportion to the required speed of the motor.

The STK681-320 motor driver has many uses, from simple hobbyist and educational applications to sophisticated industrial applications. For instance, it can be used in robotic systems, consumer electronics, medical devices, automotive, industrial automation and motion control applications. It is suitable for a wide range of applications due to its reliability, robustness and advanced features.

In conclusion, the STK681-320 is a reliable, robust and feature-packed motor driver offering enhanced speed control and safety. It is suitable for various industrial, consumer and medical applications and can be configured to work in PWM and linear analog modes. The device’s constant current limiter function provides increased safety and efficiency.
