DataSheet: PDF icon fruchbabefonbei.cf LD is a dual H-bridge motor driver integrated circuit (IC). Motor drivers act as current amplifiers since they take a low -current. LD Motor Driver fruchbabefonbei.cf DISCLAIMER. Information furnished is believed to be accurate and reliable at the time of publication. The LD datasheet specifies that this device is a monolithic integrated high voltage, high current four channel driver designed to accept standard DTL.
LD contains two inbuilt H-bridge driver circuits.
In its common mode of operation, two DC motors can be driven simultaneously, both in forward and reverse direction. 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 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.

Search Search.So if you have motors which has operating voltage less than 36V and operating current less than mA, which are to be controlled by digital circuits like Op-Amp, timers , digital gates or even Micron rollers like Arduino, PIC, ARM etc..
The most common method to drive DC motors in two directions under control of a computer is with an H-bridge motor driver. The input pins Input 1,2 are used to control the motor 1 and Input pins 3,4 are used to control the Motor 2.
You can find the necessary pin diagram, working, a circuit diagram, Logic description and Project as you read through. H-bridges can be built from scratch with bi-polar junction transistors BJT or with field effect transistors FET , or can be downloadd as an integrated unit in a single integrated circuit package such as the L Input 3. Country of Origin: If anyone of the either pin1 or pin9 goes low then the motor in the corresponding section will suspend working.
