What is the full form of L293D?
L293D Description L293D is a typical Motor driver or Motor Driver IC which allows DC motor to drive on either direction. L293D is a 16-pin IC which can control a set of two DC motors simultaneously in any direction. Dual H-bridge Motor Driver integrated circuit (IC).
What is H bridge in L293D?
An H-Bridge is nothing but an electronic circuit. Using such a circuit, you can supply current in two directions. The L293D is an H-Bridge with two possible outputs. Meaning, you can connect two things to it… and you can control the direction of current flow in both.
What are the enable pins in motor driven IC?
L293D Pin Configuration
| Pin Number | Pin Name | Description |
|---|---|---|
| 1 | Enable 1,2 | This pin enables the input pin Input 1(2) and Input 2(7) |
| 2 | Input 1 | Directly controls the Output 1 pin. Controlled by digital circuits |
| 3 | Output 1 | Connected to one end of Motor 1 |
| 4 | Ground | Ground pins are connected to ground of circuit (0V) |
What is L293D for?
The L293D is designed to provide bidirectional drive currents of up to 600-mA at voltages from 4.5 V to 36 V. Both devices are designed to drive inductive loads such as relays, solenoids, DC and bipolar stepping motors, as well as other high-current/high-voltage loads in positive-supply applications.
How is the l293d IC used in a motor?
The other ICs could have the same functions like L293d but they cannot provide the high voltage to the motor. L293d provides the continuous bidirectional Direct Current to the Motor. The Polarity of current can change at any time without affecting the whole IC or any other device in the circuit.
How many DC motors can a l293d Shield Drive?
L293D shield is a driver board based on L293 IC, which can drive 4 DC motors and 2 stepper or Servo motors at the same time. Each channel of this module has the maximum current of 1.2A and doesn’t work if the voltage is more than 25v or less than 4.5v.
What do you need to know about the L293?
Features and Specifications The L293 and L293D devices are quadruple high current half-H drivers. The L293 is designed to provide bidirectional drive currents of up to 1 A at voltages from 4.5 V to 36 V. The L293D is designed to provide bidirectional drive currents of up to 600-mA at voltages from 4.5 V to 36 V.
Which is the H bridge of l293d IC?
L293D is, infact, a dual H bridge IC used to drive motors in both forward and backward direction through various combinations of inputs that we will look later. The first H-Bridge is formed by Left Hand Side pins of L293D (see diagram) while the second is formed by the right hand side ones.
