Power Management ICs have revolutionized the way motors and other electrical devices, such as lights and pumps, are controlled in commercial, industrial, and automotive applications. SLA7073MR is a motor and load driver integrated circuit (IC) manufactured by Sanken Electric. It is a multi-functional IC that can be used in a wide range of applications, from controlling motors and solenoids to providing current limiting for LEDs, buzzers, and lamps.

The SLA7073MR integrates a low-voltage control circuit, low-side, and high-side power MOSFETs into a single package. It contains two MOSFETs connected in series to provide over-current protection and current limiting. This IC integrates a ramp generator and PWM comparator for controlling the output, making it capable of driving brushed or brushless DC or stepper motors.

The main benefit of using the SLA7073MR is its high performance level. It has a wide voltage input range, allowing it to be used in a variety of applications. Its internal MOSFET provides protection against over-current and over-voltage conditions, making it very reliable. The superior current limiting feature prevents it from overloading and keeps it in compliance with the safety requirements of different standards. It also has a wide operating temperature range and can function even in extreme temperatures.

In motor control applications, the SLA7073MR is used to provide speed and torque control, as well as current limiting for motors. The speed and torque control are achieved by configuring the voltage of the power supply and the PWM frequency. The current limiting feature allows for current limiting of the motor when a certain limit is exceeded. This prevents the motor from stalling or overheating, as well as from damage due to overcurrent.

The SLA7073MR is also used in automotive applications to control the speed and direction of an electric motor. It can be used for steering and for powering solenoids, lights, and other electrical devices. It is capable of controlling up to 25A of continuous current, making it suitable for controlling high-power motors.

In LED lighting applications, the SLA7073MR can be used as a current limiter. It is capable of limiting the current up to 25A, making it suitable for LED lights. The LED current limiter feature ensures that the LED lights do not overload and that they stay in compliance with the desired current level.

The SLA7073MR is also used in buzzer and speaker applications. The PWM comparator provides a high-efficiency control of the output voltage and current with minimal switching loss. This feature prevents the buzzer from overheating and from making too much noise. The IC also has a wide range of control options, making it suitable for a variety of applications.

Overall, the SLA7073MR is a versatile and highly efficient motor and load driver IC that can be used for a variety of applications. It is capable of providing speed and torque control, current limiting, and protection against over-current and over-voltage conditions. It is highly reliable and can function in extreme temperature conditions. It is also suitable for controlling a wide range of motors, LEDs, buzzers, and other electrical devices.
