Powerstep01 goto at specific speed
Hi, I'm using the powestep IC to control a stepper motor. All is going well but I can't figure out how to move the motor from one point to another at specific speed. e.g. if I send the goto command, like goto(1000) the motor do Accel--->max_speed-->D...
What's happening with the LD39300PT-R voltage regulators?
Anyone knows what's happening with the productoion of the voltage regulator LD39300PT-R? I am trying to buy this component for weeks and all distributors have no stock of this part number. The factory delivery time, in every distributors is 50 weeks!...
LDL212 datasheet mistake
Hi,There is a datasheet on digikey page related to LDL212 product wihch shows pin1 is Output Voltage but the datasheet on ST website shows pin1 is Ground.I beleive there is a mistake on datasheet on digikey page.A picture is attached thanks.

H bridge VNH7100BAS application
Posted on July 03, 2018 at 07:54Hello: I am try to use the H bridge VNH7100BAS to design the Single-phase motor's driver.The block diagram as below: Hall sensor detects the location of winding's rotor magnetic pole. According to the position, mot...
Zero (and almost zero) ST FOC speed performance
Looking for some advice for some specific performance improvement.I am working on a traction application with custom inverter hardware and ST FOC software. Also using custom motors with built in hall sensors. The application uses the motors for movem...
I am using VIPER22A-E in one of my design. Shall I get the design equations used for pi filter values used in the evaluation board.

STLD41 PWN IN pin not used
Posted on July 26, 2017 at 10:57If I don't need to dim the LED current, what is the correct usage of the PWM pin of STLD41?Thank you
How do I determine a value for Ke for the stepper motor I am using?
I'm experimenting with the EVAL6470H dev board and the Spin Family software. I can get the values for motor inductance and motor winding resistance for the motor I want to use but I cannot find a spec for the Ke value.Can anyone help me understand h...
L6472 Stepper Driver - Does the max/min speed register value conform to the selected step mode or is it always in terms of whole steps?
I am driving a 200 step per revolution motor. The position register per the data sheet conforms to the selected step mode so 1/16 micro stepping results in 3200 steps per revolution. I would expect that the max/min speed registers would conform to ...
