Discuss power management solutions. Ask questions and find answers on voltage configurations, short circuit protection, and programming.
Posted on July 09, 2013 at 00:07I've gotten past all of my comms issues and seem to be able to talk to the L6470 reliably now. However, I'm having trouble actually getting it to move. I keep getting OCD events even when commanding moves at low acc...
Posted on May 24, 2018 at 15:02Can you share with us time response and turn off time of the STEF01 electronic fuse against high surge currents in detail? Do you provide any application note for this device againts lightning induced transients, inrus...
Posted on May 24, 2018 at 09:31Dear All,I have been working on a project where I need to Switch on Two devices using Two BTA06 controlled by Digitally Opto-Triac. Line and Neutral are same for both.Attached is the schematic.I have issue that when I ...
Posted on May 23, 2018 at 19:49I am using an IHM02A1 board with a Nucleo F401RE. I have ported the drivers into a new CubeMX project and I can run the example program. The example program's stepper parameters (in parameters.c) seem to be working but...
Posted on May 04, 2018 at 19:12The L6227Q looks like just the part I want to control a small motor that will run at about 5V and no more than 300mA. I was looking at Table 7 in the data sheet. I think what I want is to set IN1 and IN2 to the polar...
Posted on May 21, 2018 at 15:12Hi, I wondered if there were any other appropriate methods for heat sinking of the VNH7070AS H-bridge motor driver instead of using the PCB substrate?? I would ideally like to use a traditional metal heat sink instead ...
Posted on May 12, 2018 at 19:44 We used BT139X-600E triac. Opto triac MOC3052 used for triac's control. Load is 230V, 50 Hz LED lamp, current is 30 mA. Current is not very nonlinear - it is short 'pulses' in the maximum of voltage 230 V. The triac...
Posted on February 07, 2018 at 17:51Hello, I am new to STM32 and to ST products in general. I am developing a BLDC motor controller. Until now we've been working with other MCU development platform but we want to research other solutions as well. ST...
Posted on May 17, 2018 at 15:24I would need advice on how to make a stepper motor drive with a supply voltage of 120Vdc and a current of 6 nominal Amps.It seems to me there are only 2 ways, even if I do not know if they are feasible, they are:1) Use...
Posted on March 21, 2018 at 20:50 I found only more requests of the same in this forum and no answers. Using Hall sensors for motor control is most typical today. 6-step BLDC code example provided in X-CUBE-SPN8 is sensorless only. There are driver...
