L6474 Charge pump low...only 5 volts
Posted on June 26, 2014 at 03:57I'm builting a mini drive using the L6474. Got it all working and it runs smooth, but the driver runs very hot and I measured the charge pump and the voltage is only 5volts p-p max (manual says it should be 10vp-p) ...
L6470 get ABS_POS: 8th Bit always Low
Posted on November 30, 2012 at 16:43Hello ST!We are using the L6470 and it is working quite well. But: We have problems when reading the ABS_POS register. It seems to be that the 8th Bit (for 128) is always Low. See Our values: Go To Pos R...
Problems in Configuration of my L6482 board
Posted on March 23, 2014 at 11:37I have designed a board using a L6482 chip. My L6482 has started, and I can send and receive messages a través de SPI bus, but now I have a problem: My STATUS register says: 1110 0000 0000 0011 (Get Status Command =...

L6470
Posted on June 03, 2012 at 21:47hi , i am currently evaluate l6470 and have a few questions : 1. does the driver suitable for stepper motor with max 3A current per phase ? 2. how to obtain maximum holding torque ? ( setting K_HOLD to FFh ?) #go_u...
L6474 grounding/layout recommendations
Posted on June 03, 2014 at 11:22The L6474 chip provides three ground pins (PGND, AGND, DGND) as well as a thermal pad (EPAD) connected internally to all three of the above. If I understand the chip's block diagram correctly (datasheet, p. 7), PGND a...
L6470 Power ON and RESET
Posted on June 20, 2014 at 07:29HiI'm using L6470.It works to move step motor a bit,when the Powered on.The motor's coil Voltage was high between the RESET turn high and First SPI communication is started.(Almost 10ms?CPU's order)I don't want to m...
Step-Clock Mode
Posted on June 17, 2014 at 11:15Dear all,I actually using two l6470 boards (to control two stepper motors), connected in daisy chain configuration also with STM32F4DIS-EXT.I don't understand very well how to control these drivers in STEP-CLOCK mode....
