L293D motor drivers are commonly used as an interface between microcontrollers (like Arduino, Raspberry Pi) and motors. The microcontroller signals are too weak to directly drive most motors. This is where the L293D comes in to amplify the microcontroller’s signals, providing the necessary current and voltage to power the motors. Here’s a simplified view of how the L293D helps you control your motors:
- Signal Amplification: The L293D boosts the control signals from your microcontroller.
- Direction Control: It allows you to easily control the direction of rotation (forward, backward).
- Motor Isolation: It isolates the microcontroller from the motor’s potentially noisy electrical environment.
The L293D is a dual H-bridge driver, allowing it to control two DC motors independently. Each H-bridge consists of four switching elements that allow for bidirectional current flow to the motor. The truth table in the datasheet precisely describes the required logic input combinations to achieve specific motor movements. For example, to drive a motor forward, you’ll need to enable the appropriate input pins high while keeping others low, as specified by the datasheet. Similarly, the datasheet outlines how to stop the motor or reverse its direction. It contains a wealth of other critical data, some of which are listed below:
- Maximum Supply Voltage
- Output Current Capability
- Operating Temperature Range
| Parameter | Value |
|---|---|
| Supply Voltage (VCC1) | 4.5V to 7V |
| Supply Voltage (VCC2) | 4.5V to 36V |
