L293D USER GUIDE USER GUIDE FOR L293D MOTOR DRIVER BOARD 1 K-IMAGINATIONS | www.kimaginations.com L293D USER GUIDE Introduction: The L293D is a monolithic integrated high voltage, high current four channel driver designed to accept standard DTL or TTL logic levels and drive inductive loads (such as relays solenoides, DC and stepping motors) and switching power transistors. Features: Light weight, small dimension Super driver capacity Two enable inputs are provided to enable or disable the device independently of the input signals 2 DC motor/ 4 coil dual phrase stepper motor output 4 standard mounting holes Specifications: Driver: L293D Driver power supply: +7V ~ +36V Driver peak current: 1.2A Logic power output Vss: +5 ~ +7V (internal supply +5V) Max drive power: 5W Working temperature: -40 oC ~ +150 oC Dimension: 50mm*40mm *20mm (l*b*h) 2 K-IMAGINATIONS | www.kimaginations.com L293D USER GUIDE Hardware connection: 3 K-IMAGINATIONS | www.kimaginations.com L293D USER GUIDE Pin configurations: Double H driver module can drive two DC motors at the same time. The board has a total of 20 pins. Enable 1 & 5V: These pins are to be shorted with a jumper if the input signals have to control the motors, if in case the control of the motors is dependent on the microcontroller data then the enable pin has to be connected to the controller data pins. Enable 2 & 5V: These pins are to be shorted with a jumper if the input signals have to control the motors, if in case the control of the motors is dependent on the microcontroller data then the enable pin has to be connected to the controller data pins. Digital port D1,D2,D3,D4:These four pins are used to control the direction of the motor. D1 and D2 for one motor & D3 and D4 for the other motor. For example D1=0, D2=1, motor 1= forward & D3=0, D4= 1, motor 2= forward. Similarly if the data is D1=1, D2=0 & D3=1, D4=0 the motors will rotate in reverse direction. 5V, G, D3:The three pins are to be used when a sensor has to be interfaced directly for the motor control. Sensor supply is on board and the pin D3 is to be connected to the output of the sensor which will be control pin of one motor. 5V, G, D1:The three pins are to be used when a sensor has to be interfaced directly for the motor control. Sensor supply is on board and the pin D1 is to be connected to the output of the sensor which will be control pin of other motor. D2, G:These two pins are to be short using a jumper when sensor is directly interfaced for the motor control. D4, G:These two pins are to be short using a jumper when sensor is directly interfaced for the motor control. 4 K-IMAGINATIONS | www.kimaginations.com L293D USER GUIDE Table for enable and digital port: ENABLE 0 1 1 • D1 D2 D3 D4 (Motor 1) (Motor 1) (Motor 2) (Motor 2) DIRECTION OF THE MOTORS 0 0 1 1 1 0 0 0 1 1 1 0 No change Clockwise Anticlockwise Actual Hardware connections: Ordering Information K-IMAGINATIONS, Pune 9960860390 E-mail us at:[email protected] , [email protected] K-IMAGINATIONS | www.kimaginations.com 5
