I recently started a project that was designed to use servos or a motor driver. The servo part was very well documented however te motor driver part had like two sentences that basicly said the motor driver's data sheet would tell you how to set it up. I under stood most of the things on the data sheet except wheredo you hook upthe motor and how to send the signal from arduino to the motor driver. the data sheet is at http://focus.ti.com/lit/ds/symlink/tpic2101.pdf I searched for anyone else with a well documented use of the tpic2101 but i have not found any. If you could send me links or circut designs that have been used with the tpic 2101 it would be great thanks

 

I have used the TPIC2101 in manual mode. I suspect you want to use the auto mode and are generating a pwm with mcu. In any case, here is the circuit I used to control motor speed with a few resistors. The mosfet driver is the LT1158.

Ok thanks for the help. I just got everything laid out on a breadboard
