Sorry for my poor english. The most common method to drive DC motors in two directions under control of a computer is with an H-bridge motor driver. Post as a guest Name. Data sheet PDF fileKb.

A more recent, improved specification, pin-for-pin compatible chip is recommended for new designs: Actually i just want to control dc motor rotation direction, it turn left or right So, the tutorial i found in this link below http: James there are some diodes in the normal are they not the ones that protect against inductive spikes?

LD has output clamping l923ne for inductive transient suppression while the LNE does not. Sign up using Facebook. The diodes in the D are indeed there to protect against inductive spikes.

Pick the “D” version because it has built in flyback diodes to minimize inductive voltage spikes.

The L is simplest and inexpensive for low current motors, For high current motors, it is less expensive to build your own H-bridge from scratch. See the datasheet for how they are connected.


Pin 1 is at the top left when the notch in the package faces up. Assume you have only one motor connected with the enable tied to Arduino Pin 3, and the two direction controls tied to Arduino Pins 4 and 5. If you are only using one motor, leave L pins 9, 10, 11, 12, 13, 14, and 15 empty. They are much cheaper than a new If it gets too hot to touch, you can’t use it with your motor. Hook up the circuit and run your motor while keeping your finger on the chip.

Them D has built-in protection diodes. Capacitor Expert By Day, Enginerd by night. Note to ME students: Sign up or log in Sign up using Google. I thought they might be the ones everyone knows about connecting across an inductive load when switching it with a transistor, but the data sheet says both varieties are good for inductive loads So presumably they serve some other protective purpose?

Quadruple Half-H Drivers

Help me please and thanks you so much for your attention. James, yes I see from the data sheet that there are extra diodes in the D, but exactly what protection do they provide?

I see too, that the the D can only handle mA compared to 1A. Home Questions Tags Users Unanswered. Unsure about whether the L will work with your motor? The following schematic shows how to connect the L to your motor and the Arduino. The L comes in a standard pin, dual-in line integrated circuit package.

I prefer going to an ICs datasheet: If you can only find the LNE you can add your own diodes. Personally I still use external diodes with the D.

See notes below for a two Arduino pin solution.

LNE from Texas Instruments

Note that the names for pin functions may be slightly different than what is shown in the following diagrams. Tutorials on that site are have been known to be wrong. The pinout for the L in the pin package is shown below in top view. The L is an integrated circuit motor driver that can be used for simultaneous, bi-directional control of two small motors. What is the difference datasheer google could not tell me?
