What is L-298
L-298 belongs to IC family and available in two main categories of packages. It provides features to bear a large value of current and voltage. Through this module, there are different devices such as dc motor, stepper motor, which are operating. Its basic function is based on the TTL or transistor transistor logic. The main circuitry which it used is in motor controllers. These controllers are operated through the use of Arduino, PIC, etc.L298 get input from theses controller and operate the load linked to this module. There are two pinouts for PWM are assembled on this board. that regulate the speed of the motor. The common application of this module is robotics, CNC machines, or automatic door lock system.

Where to Use L298 IC
- The main usage of this IC is explained here.
- In H BRIDGE circuit configuration, it mostly used.
- To run high-power motor driver circuits, it used. For such applications where lower power is required L293 is used and for high-power applications, L298 is preferred.
- Such devices that are controlled through the PWM and current control is needed that IC is used.
- For such a control unit that offers TTL outputs it used..
