Hi,
I followed all the instructions to make the motor control board using L6206N given in 9944.pdf (https://www.st.com/stonline/books/pdf/docs/9944.pdf) and in its datasheet. I am supposed to make it work wiht my microcontroller. But I don't know why it is being hot during operation. I tried 12v 1A DC power supply and 12v 7.2 AH battery.
Is it normal being hot during operaiton? Or anything did I miss? How would I check if anything is going wrong in that circuit?
Hi Fireball,
My experience with ST chips says that it shouldn't desipate heat when driving the motor. Try adding a tantallium capacitor of say 10uF in parallel to the motor phase and a 50 ohm resitor in series with the motor.
I have suggested this, to make possible impedance match between the chip and motor. See if this works.
