Output Current 1 A Per Channel (600 mA for L293D).Wide Supply-Voltage Range: 4.5 V to 36 V.L293 and L293D are characterized for operation from 0☌ to 70☌. This ic can drive 2 motors simultaneously in.
#L293d motor driver circuit drivers#
Drivers are enabled in pairs, with drivers 1 and 2 enabled by 1,2EN and drivers 3 and 4 enabled by 3,4EN. L293D IC is a bidirectional motor driver IC means it can drive DC motor to rotate or run in either direction. 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.Įach output is a complete totem-pole drive circuit, with a Darlington transistor sink and a pseudo- Darlington source.
The L293D is designed to provide bidirectional drive currents of up to 600-mA at voltages from 4.5 V to 36 V. The L293 is designed to provide bidirectional drive currents of up to 1 A at voltages from 4.5 V to 36 V. The L293 and L293D devices are quadruple high current half-H drivers. If your motor matches these specifications, do not hesitate to use L293D. However, it can withstand a current up to 1200 mA in 100 microsecond and non-repetitive. This IC can set up motors with a voltage between 5V to 36V and a current of up to 600 mA. There are several reasons which make L293D the preferred driver to the users, such as, cheap price (compared to other drivers), proper shape and size, easy control, no need for protective circuit and diodes, no need for heat sinks and good resistance to temperature and high-speed variations. L293D is one of the most popular drivers in the market. So we need intermediate circuits to connect the controller to the motor, called drivers. But as you know, the output of microcontrollers are 5V and 200mA and can not spin the motor.
Therefore, we must control motors using controllers (logic circuits or microcontrollers or PCs or computers). One method is to connect it directly to a battery, then it spins at its maximum speed in a particular direction, but in practice, we need to control the motors (on and off, speed control, direction control, and position control). This IC can drive inductive loads such as motors, Relays, Solenoids, and bipolar stepper motors. The L293D is capable of providing bidirectional drive currents up to 600mA at voltages from 4.5V to 36V. Depending on the model, the manufacturing method, price, etc., their current is about 100 mA to 5A. IC L293D from Texas instruments is a quadruple high current half-H driver. Motors used in academic robots normally operate at 5, 6, 9, 12 or 24 volts.
