Product Overview

The L293 and L293D are quadruple high-current half-H drivers. These devices are designed to drive a wide array of inductive loads such as relays  , solenoidsDC and bipolar stepping motors , as well as other high-current and high-voltage loads. All inputs are TTL compatible and tolerant up to 7 V. Each output is a complete totem-pole drive circuit, with a Darlington transistor sink and a pseudo-Darlington source. Drivers are enabled in pairs, with drivers 1 and 2 enabled by 1,2EN and drivers 3 and 4 enabled by 3,4EN.


When an enable input is high, the associated drivers are enabled, and their outputs are active and in phase with their input  s. When the enable input  is low, those drivers are disabled, and their outputs are off and in the high-impedance state. With the proper data inputs, each pair of drivers forms a full-H (or bridge) reversible drive suitable for solenoid or motor applications.


On the L293 external high-speed output clamp diodes should be used for inductive transient suppression. On the L293D, these diodes are integrated to reduce system complexity and overall system size. A VCC1 terminal, separate from VCC2, is provided for the logic inputs to minimize device power dissipation. The L293 and L293D are characterized for operation from 0°C to 70°C.

FAQ about L293DNE

1.How does an L293D work?

The L293D IC receives signals from the microprocessor and transmits the relative signal to the motors. It has two voltage pins, one of which is used to draw current for the working of the L293D and the other is used to apply voltage to the motors.


2.How many motors can be controlled using L293D?

Two DC motors.The L293D is a 16-pin Motor Driver IC which can control up to two DC motors simultaneously, in any direction.


3.Which is better L293D vs L298N?

L293D Drivers Operates at 4.5V to 36V whereas L298N can be Operates at up to 46V. Maximum 600mA Current can be drawn through both channels of L293D whereas L298N Motor Driver can draw up to 2A from both channels.


4.How does L293D control motor speed?

The L293D quadruple half-H drivers chip allows us to drive 2 motors in both directions, with two PWM outputs from the Arduino we can easily control the speed as well as the direction of rotation of one DC motor.


5.How do you use the L293D motor driver Arduino tutorial?

Connect Vcc1 pin to 5V output on Arduino. Make sure you common all the grounds in the circuit. Now, the input and enable pins(ENA, IN1, IN2, IN3, IN4 and ENB) of the L293D IC are connected to six Arduino digital output pins(9, 8, 7, 5, 4 and 3). Note that the Arduino output pins 9 and 3 are both PWM-enabled.


6.What is L293D H-Bridge?

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. Lets say you have a DC motor, as in the diagram below: An H-Bridge in terms of switchesIf you close both S1 and S2, you'll short circuit the entire thing.


7.What is a half H Driver?

half-H-bridge drivers. The device is intended to drive. – Drives 3-Phase Brushless DC Motorsa three-phase brushless DC motor, though it can also. – IndividualHalf-BridgeControl.


8.How many half H bridge drivers L293D consist of?

L293d ic is same like an h bridge circuit with two channels. It has two half h bridge circuits residing in it. You can use it to drive uni polar, bi polar stepper motors, dc motors or even servo motors.


9.How many motors can a l 293 motor driver control?

The L293D is a dual-channel H-Bridge motor driver capable of driving a pair of DC motors or one stepper motor. That means it can individually drive up to two motors making it ideal for building two-wheel robot platforms.


10.What happens when en1 pin of L293D is enabled?

There are 4 INPUT pins, 4 OUTPUT pins and 2 ENABLE pin for each motor. Pin 1: When Enable1/2 is HIGH, Left part of IC will work, i.e motor connected with pin 3 and pin 6 will rotate.
