Hi.   I'm currently using the L6491 to perform a current-mode capacitor charger. Structure is simple : a resistor is in line inserted after the self and before the capacitor. An high speed comparator with programmable hysteresis deliver the command to Hin and Lin (tied together). Both frequency and duty cycle are variable, it's funny !… (Show more)

Hello,   I'm using the EVAL6472H evaluation kit to experiment with the L6472 driver. I'm having trouble with the hold current setting, when is set the hold current to 200 mA for example, only 70 to 100 mA flows through the motor. When i use a higher current setting, more current will flow through the moter. The current flowing through the motor… (Show more)

Hi Abnormal over current detection behaviour on stepper motor controller L6480. After initialization a hard stop command is given to hold the stepper motor, which seems to work just fine, all the expected waveforms appear on the gates of the transistors. When a move command of 128 micro-steps are given the bridge disengaged with no errors in the… (Show more)

Hi, When I am using the BEMF compensation configuration within the SPINFamily Evaluation Software, I input the Application Parameters and the Motor Parameters for my particular motor.        When I press the ‘Evaluate’ button at the bottom right of the menu, the following Device Configuration Values are calculated: KVAL_HOLD KVAL_ACC… (Show more)

We are using FET STL26NM60N on a PCB that we sell. These are now only available as tape and reel, in quantities of 3000, which is 25 years' supply  for us. Can anyone suggest a direct replacement? STL23NM60ND and STL33N65M2 look promising. Thanks, Matt.

Anybody who can teach me how to use a powerstep01 to drive the step motor? I have the demo boards and the powerstep01 works well with the demos and the download software from st.com. Now, i want to use another MCU (low price) to drive the step motor with powerstep01, but i found the software is very hard to understand, and it is hard to adjust… (Show more)

I am using L9823 in my design to drive the outputs. I also want it to behave as input so that I can connect IO module. How can I use it as input?   Thanks in advance
