The L is limited to mA, but in reality can only handle much small currents unless you have done some serious heat sinking to keep the case temperature down.

Johannesburg hams call me: Tutorials on that site are have been known to be wrong. A more recent, improved specification, pin-for-pin compatible chip is recommended for new designs: If you are only using one motor, leave L pins 9, 10, 11, 12, 13, 14, and 15 empty.

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. Note that the names for pin functions may be slightly different than what is shown in the following diagrams. Data sheet PDF fileKb. The diodes in the D are indeed there to protect against inductive spikes. Help me please and thanks you so much for your attention. The L is simplest and inexpensive for low current motors, For high current motors, it is less k293ne to build your own H-bridge from scratch.

Sorry for my poor english. Personally I still use external diodes with the D. Unsure about whether the L will work datqsheet your motor? dataxheet

The L is an integrated circuit motor driver that can be used l2993ne simultaneous, bi-directional control of two small motors. I prefer going to an ICs datasheet: If you can only find the LNE you can add your own diodes.

Quadruple Half-H Drivers

So presumably they serve some other protective purpose? Datashert are much cheaper than a new Capacitor Expert By Day, Enginerd by night. Home Questions Tags Users Unanswered. See the datasheet for how they are connected.

Pick the “D” version because it has built in flyback diodes to minimize inductive voltage spikes. The L comes in a standard pin, dual-in line integrated circuit package.

driver – What is the difference between LD and LNE? – Electrical Engineering Stack Exchange

H-bridges can be built from scratch with bi-polar junction transistors BJT or with datashee effect transistors FETor can be purchased as an integrated unit in a single integrated circuit package such as the L Sign up using Facebook.

If it gets too hot to touch, you can’t use it with your motor. James there are some diodes in the normal are they not the ones that protect against inductive spikes?

Pin 1 is at the top left when the notch in the package faces up.

Actually i just want to control dc motor rotation dztasheet, it turn left or right So, the tutorial i found in this link below http: What is the difference even google could not tell me? The pinout for the L in the pin package is shown below in top view. Hook up the circuit and run your motor while keeping your finger on the chip.

There is an L and an LD part number. LD has output clamping diodes for inductive transient suppression while the LNE does not. See notes below for a two Arduino pin solution. Sign up using Email and Password. 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 James, yes I see from the data sheet that there are extra diodes in the D, but exactly what protection do they provide?
