I have problem with wiring L – Ln. The wiper of the potentiometer goes to the Vref pin.
Do you have a link to the type of motor and motor specs? You Might Also Like [ Hide ].
Buy Direct Add to cart. BTW I also haven’t connected anything to pin 17 and 18 because I know they are inputs. Anything smaller allows more current and risks burning out the L Probably the best approach to solving the problem would be to “divide and conquer” – break down the problem into little pieces that you can solve one at a time.
Not connecting the Vref pin is probably your most serious problem.
However my Datashert heats up very quickly whenever I test the circuit so I suspect it is because of those pins. The SGS Thompson LD is one of the most common motor driver chips, with built-in protection from the abuse motors can create. Personally, I have no idea how to control parallel ports on computers, but I’m sure somebody here knows how to do that.
General terms and conditions. It is not required, but is encouraged as a way to reward the people who take the time to provide answers. Sign up or log datassheet Sign up using Google. Support Home Video Center. Since the phase are generated internally the burden on the microprocessor, and the programmer, is greatly reduced.

As you can see on the diagram on page 2 of the L datasheet, this is the reference voltage which goes to internal comparators and is compared to the voltages coming from the current-sense resistors. Than i wired the schematic with leds without Ln than i understood how it works.
Thank u so much The circuit should perform acceptably with this line either tied to l279 high 5V or logic low GND. Now 2 things remains. Redrachet2 32 1 2 Please contact our sales support for information on specific devices.
Also consider accepting an answer to any of your questions that solves your problem. Product is in volume production. Please read the fine datasheet RTFD and learn what the outputs are used for. Don’t Have an Account?
U were right ; the first one’s pin 4 burned so i changed it with a new one. I build it again but this time without Ln and and i put 4 leds to the output of the L
