# Report on L293D Motor Driver IC
**What is a L293D Motor Driver?**
The L293D Motor driver is a high current half-H driver. This device is designed to drive a wide array of inductive loads such as DC, relays and stepper motors, as well as other high-current and high-voltage loads. This motor driver is a 16-pin IC (Integrated Circuit) allowing us to control 2 DC Motors or 1 stepper motors speed and direction.

**Features:**
- Wide supply voltage range (4.5V to 36V)
- Seperate Input logic supply.
- High noise-immunity inputs.
- Output current 600mA per channel.

**Applications:**
- DC motor drivers.
- Stepper motor drivers.
- Latching relay drivers.


**What is an H-bridge?**
An H-bridge is an electronic circuit consisting of four switches (usually MOSFETs or transistors) arranged in an "H" configuration around a load—typically a DC motor allowing it to run forward, backward or brake by reversing the voltage polarity. It enables bidirectional control in robotics, power inverters, and motor drivers.

**PWM (Pulse Width Modulation):**
PWM (Pulse Width Modulation) is used with the L293D motor driver primarily to control motor speed without sacrificing efficiency. Since the L293D acts as a high-speed switch, sending a PWM signal to its Enable pins rapidly toggles the motor power on and off by varying the duty cycle, which changes the average voltage delivered to motor directly regulating its RPM.
