l6208
hello,
now i am doing a project. it is driving a stepper motor by L6208.
the datasheet of L6208 said that it can support a current 5.6A, but now, it only support 1A.well the torque is not enough. if i want a higher torque, what should i do.
P.S.:my circuit is samilar with the one...
atmega isl1208
i use the ISL1208 for RTC,but i dont know clearly how to control it by ATMEGA 128.
and my mainly question is how to control the registers.
if anybody who konws that and give me some advices, i will appreciate help.
sla7062 step motor control schematics
hi edison.
seems a late reply.
I have finished that project. now samples are made by workers. I control the SLA7062 directly by mcu, and you? but seems that your surrounding circuit is so complex.

edison, the website doesn't work.
I have finished that project. now workers are making 10 samples to test. I am so happy that I finished it befor 2006. thanks a lot,Ahmed Ragab & amrstaha.
Hi all, remember me?
I drove a stepper motor with four phases and six wires by SLA7062, it can move now, but what should I do then.
I change the speed of motor by changing the frequency of CLK.
sla7062 project
hi all, im back.
i have new question.i want to select a p-channel mosfet,but what i found is that they all have high voltage,and high current.finally,i choose the 2N6845. did you here that before?could you give me some advices. thankyou
reset cct for sla7062
Thank you IanP, you mean if i give 0V to gate, this mosfet will be open, and the Vref is equal to Vdd. but i should make sure that the voltage of Vref is 0.1V~2V.So i must give 5V to the gate,and ensure that R1 is effective,right?
im a newbie on control of stepper motor...
driver sla7062
Thank you Ianp, i got it, ^_^

i have another question,
in the figure of page 11, i think Q1 is wrong,should it be reverse. i think the direction is from S to G,not from G to S.

Thank you Ianp, i think i can go on my design, ^_^

i have another question, in the figure of page 11, what does the P-GND and the S-GND mean,
sla7062 project step mortor
Thank you Ianp, i think i have understanded meaning of you and VVV. It is due to the current control mode. So, thank you.
And i have another qustion, if i use that chip, all the input voltage is logic, high or low, and no PWM input, right?
sla 7062
Thank you VVV, but i still cant understand the question 2, about voltage of VBB, is it equal to the input voltage of my motor? and the rated voltage of my motor is 6.6V, but VBB should be from 10 to 44V.
Thank you :D

sla7062
hello everyone.
did anybody use the SLA7062 to drive and control the stepper motor?
i cant understand something
1\what does the SYNC use for?
2\the rated voltage of my motor is 6.6V,but VBB is just from 10V to 44V, what should i do? connect them directly?
3\are the RsA and the RsB same...
