How to use BTS7960BMotor DriverIC?

The BTC7960B is a high-powerMotor Driver IC.As the name implies it’s mainly used to drive motors. As it is ahalf-bridge motor driver IC, you need two of these ICs to rotate theDC motorbidirectionally, the operating voltage of this device is greater than 40V so it can drive pretty beefy motors with an operating current of 600mA so it can be driven by amicrocontrolleror a555 timer ICto generate a PWM signal that can control the speed of the motor for additional safety measure aULN2003 ICand be used as a buffer.

As you can see in the above picture using this IC is pretty simple the datasheet of the device attached below gives us the schematic shown above, the circuit and connections are pretty simple, and the two motor drivers in anH-bridgeconfiguration is used to drive a motor so that the motor can be rotated in both reverse and forward direction, as we have previously said themicrocontrolleris used to provide aPWM signalthat can be used to control the speed of the motor. By alternating the driving direction, the motor can be rotated either clockwise or any clockwise, this is a pretty popular IC and if you are testing this IC for your design then there are prebuilt modules available in the market that can you can use for testing purposes and those modular are compatible with Arduino one of such module is shown below.
