Help me please and thanks you so much for your attention. 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 Pin 1 is at the top left when the notch in the package faces up.

Sorry for my poor english. H-bridges can be built from scratch with bi-polar junction transistors BJT or with field effect transistors FETor can be purchased as an integrated unit in a single integrated circuit package such as the L Johannesburg hams call me: The L comes in a standard pin, dual-in line integrated circuit package.

A more recent, improved specification, pin-for-pin compatible chip is recommended for new designs: The following schematic shows how to connect the L to your motor and the Arduino. James, yes I see from the data sheet that there are extra diodes in the D, but exactly ll293ne protection do they provide?

Note that the names for pin datasheft may be slightly different than what is shown in the following diagrams. LD has output clamping diodes for inductive transient suppression while the LNE does not.

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. Since you’re going to drive a motor you will want to use clamping diodes to avoid inductive spikes from the motor killing the output transistors in the chip.

The diodes in the D are indeed there to protect against inductive spikes. The most common method to drive DC motors in two directions under control of a computer is with an H-bridge motor driver. Sign up or log in Sign up using Google.

If you can only find the LNE you can add your own diodes.

Note to ME students: Them D has built-in protection diodes. The L is an integrated circuit motor driver that can be used for simultaneous, bi-directional control of two small motors.

So presumably they serve some other protective purpose? Capacitor Expert By Day, Enginerd by night. 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. They are much cheaper than a new Each motor takes 3 Arduino pins. See notes below for a two Arduino pin solution. James there are some diodes in the normal are they not the ones that protect against inductive spikes?

Personally I still use external diodes with the D. Sign up using Facebook.

If you are only using one motor, leave L pins 9, dataxheet, 11, 12, 13, 14, and 15 empty. I see too, that the the D can only handle mA compared to 1A.

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

If it gets too hot to touch, you can’t use it with your motor. 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: Email Required, but never shown. There is an L and an LD part number.
