What is the maximum current L293D IC can withstand?
L293D ACTIVE 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.
What is L293D IC?
L293D IC is a typical Motor Driver IC which allows the DC motor to drive on any direction. This IC consists of 16-pins which are used to control a set of two DC motors instantaneously in any direction. It means, by using a L293D IC we can control two DC motors. As well, this IC can drive small and quiet big motors.
What are the H bridges in l293d IC?
L293D consist of two H-bridge. H-bridge is the well-known process to control a low current rated motor. H-bridge is a circuit which allows the voltage to be flown in either direction. In above diagram, the arrow on the left points to the higher potential side of the input voltage of the circuit.
What do you need to know about the l293d?
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: If you close both S1 and S2, you’ll short circuit the entire thing. Same goes with S3 and S4.
Where are the pins on a l293d IC?
The IC LM293D consists of 4-i/p pins where, pin2 and 7 on the left side of the IC and Pin 10 and 15 on the right side of the IC. Left input pins on the IC will control the rotation of a motor. Here, the motor is connected across side and right i/p for the motor on the right hand side.
What kind of IC is used for H bridge?
Hence, H-bridge circuit using L293D ICs are perfect for driving a motor. Single L293D IC consists of two H-bridge circuits inside which can rotate two DC motors separately. Generally, these circuits are used in robotics due to its size for controlling DC motors.
