Motor Driver Boards, Modules play a very important role in the automation world, and MEDLT83SF is one of them. Today, this article is going to expound on the applications and working principles of MEDLT83SF, detail in later sections.

Applications of MEDLT83SF

MEDLT83SF is a highly integrated motor driver board module manufactured by Microchip. Driven by PWM or analog input, it’s suitable for controlling brushless fan and dc motor applications in medical, commercial, and industrial applications. With fewer external component counts, it can also support motor speeds up to 5,000 RPM(revolutions per minute) with a wide range of current needs.Apart from controlling fan and motor applications, the versatile MEDLT83SF can also be used as an amplifier for a signal preamp. It can works as an adjustable gain amplifier, makes a perfect matching with other components like capacitors. Besides, it can helps to reduce the need of extremely high power requirements, making it an ideal tool for developing the electronics system.

Working Principles of MEDLT83SF

The MEDLT83SF drive board has a complete circuit within it, derived from an H-bridge and includes power stage transistors in its power circuitry. The motor is connected from one end of the bridge to the other. The motor driver board accepts inputs such as PWM signal and/or analog signal from a microcontroller.

Furthermore, depending on the level of the PWM or analog signal, the circuit will enable a certain combination of transistors, thus allowing current to flow through one side of the motor, either forwards or backwards, to drive the motor. If the positive PWM resistor is switched on and the negative resistor remains open, then the current from the positive side of the bridge will energizes, driving the motor in one direction.

Similarly, if both resistors remain open, then current will flow through both sides of the bridge, driving the motor in the opposite direction. Therefore, through these on and off logic, the module is capable of changing the motor’s rotation direction. With a 3-phase bridge, it even allowes for the motor to be driven in multiple directions.

Conclusion

To sum up, MEDLT83SF is a driver board module used for motor and fan control, preamp signal amplifying, and more. It provides high-power drive with fewer external component counts, and the motor can be driven by either PWM or analog signals. With the H-bridge design, the current can be switched on and off to control the motor’s directional rotation.
