Pages: . Stepper motor driver with L and L I want a current limiting circuit, and so I choose to use the L and the L But I have some questions. First, the motor has 2 phases, is bipolar, 1A per phase, 8. So here is the bunch of questions I have 1. There are two resistors which are called Rsense.
But what is Ipeak? In my case 1 or 2A? And what is Vref? Does this have something to do with the two ref pins? I would be glad if someone could explain this part of the circuit to me. There is a resistor between pins 16, 17 and GND. What size should it be? There are 2 enable inputs on the L Do I understand this correct, I just have to tie them to 5V if I want the chip to work? The L has a enable input too.
Same here? Do i have to look for something special for the diodes? Or will 1N do? So for the mysterious resistor without a name? The Rsense resistors will have a huge rating, I'll look for 30W resistors, right? Thank you very much! Re: Stepper motor driver with L and L Some more information I found in the datasheet of the L Quote. I found in the maximum table in the datasheet, that Vref is maximal 3V. This again would leave me with 3Ohms. And this would lead to a power dissipation of 48W on the Rsense!
What did I understand wrong? The motor windings will take 1A at 8. It the power supply was 24V or 36V or similar then this circuit would be very suitable. Here is a link to a similar chopper circuit that has links to the schmatic and the kit manual.

Two or more devices may be synchronized using the sync pin. In this mode of operation the oscillator in the master chip sets the operating frequency in all chips.
