L293D Motor Driver IC

L293D Motor Driver ICThe L293D Motor Driver IC is a dual H-bridge motor driver integrated circuit. Motor drivers act as current amplifiers since they take a low-current control signal and provide a higher-current signal. This higher current signal is used to drive the motors.The Device 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 solenoids, DC, and stepping motors) and switching power transistors. To simplify use as two bridges each pair of channels is equipped with an enable input. A separate supply input is provided for the logic, allowing operation at a lower voltage, and internal clamp diodes are included.It is suitable for use in switching applications at frequencies up to 5 kHz. The L293D is assembled in a 16 lead plastic package which has 4 center pins connected together and used for heatsinking The L293DD is assembled in a 20 lead surface mount which has 8 center pins connected together and used for heatsinking.Features –Type: Motor Drive ICModel Number: L293DOperating Temperature: 0~80Supply Voltage: 4.5 V~36 VDissipation Power: 2ACan be used to run Two DC motors with the same ICPackage: DIPPackage Weight: 0.001kg (0.00lb.)Package Size: 1cm x 1cm x 1cm (0.39in x 0.39in x 0.39in)Applications –Used to drive high current Motors using Digital CircuitsCan be used to drive Stepper motorsHigh current LED’s can be drivenRelay Driver module (Latching Relay is possible) L293D Pin Configuration –Pin NumberPin NameDescription1Enable 1,2This pin enables the input pin Input 1(2) and Input 2(7)2Input 1Directly controls the Output 1 pin.

In its common mode of operation, two DC motors can be driven simultaneously, both in forward and reverse directions. The motor operations of two motors can be controlled by input logic at pins 2 & 7 and 10 & 15. Input logic 00 or 11 will stop the corresponding motor. Logic 01 and 10 will rotate it in clockwise and anticlockwise directions, respectively. Enable pins 1 and 9 (corresponding to the two motors) must be high for the motors to start operating.When an enable input is high, the associated driver gets enabled. As a result, the outputs become active and work in phase with their inputs. Similarly, when the enable input is low, that driver is disabled, and their outputs are off and in the high-impedance state. They are designed to drive inductive loads such as relays, solenoids, dc, and bipolar stepping motors, as well as their high-current/high-voltage loads in positive-supply applications.Related Video : Arduino DC Motor Control with L293D Motor Driver ICFor more drivers, click Driver L293D মোটর ড্রাইভার IC হল একটি ডুয়াল H-ব্রিজ মোটর ড্রাইভার ইন্টিগ্রেটেড সার্কিট। মোটর চালকরা বর্তমান পরিবর্ধক হিসাবে কাজ করে যেহেতু তারা একটি নিম্ন-কারেন্ট নিয়ন্ত্রণ সংকেত নেয় এবং একটি উচ্চ-কারেন্ট সংকেত প্রদান করে। এই উচ্চতর কারেন্ট সিগন্যালটি মোটর চালানোর জন্য ব্যবহৃত হয়। Keep an eye on our website to avail the –L293D Motor Driver IC best price in BD (Bangladesh)
