L4984D

Well, I have posted a question in the eDesignSuite Q&A, but it seems to be the wrong place for it. Lets try here.I am looking for information about to feed the L4984D through self-supply. Does this controller works with self-supply or it is necessary...

How to configure POWERSTEP01 to limit Motor Phase Current

Hey,i bought <nucleo-F401RE> and <x-NUCLEO-IHM03A1> boards in order to drive the NEMA 17 "QSH-4218-51" bipolar step motor. this one can be supply under 24V with 1A phase current. Using "BASETech-305" Volage Generator, i supplie the <x-NUCLEO-IHM03A1>...

[STSPIN32F0] 6-step control: Set phase out in float mode

Hello,I am using the STEVAL-SPIN3201 board to control a BLDC motor.I want to implement a position controller, so I need to hold tight the position of the rotor at a given position (1 phase to Gnd, 1 phase to pulsed Vm, and 1 floating phase).The probl...

STC3115 Battery Status Drivers

We are working on Battery Status IC/drivers using STC3115 & purchased STEVAL-ISB014V2 from AVNET.Evaluated below drivers but still not working with Arduino also:https://github.com/st-sw/STC3115GenericDriver Changed i2c read/write, getting SLAVE ADDRE...

The maximum power of my motor is 500 w. Can the parameters here be modified? If not, what should I do?

Internal comparator OCP circuit

Hi, may I ask can move the internal comparator OCP circuit which is placed in low side MOSFET driving stage to between high side and low side MOSFET with maintain the current same firmware setting which is in ESC001V1 reference design​

Current control for L6482H at low speeds

Hello,I am developing a motor driver solution for a medical device. L648x seems to be a good option considering the current control for gate driver (which in my case will help reducing EM emissions). I already tried L6480 but I was experiencing a lot...

Example setup control system IC L6472 parametrs for target steper motor.

Dear ST.I setup IC L6472 for my steper motor and i am need example calculation sequnce for precise seti control registers/Can you write example calculation control registers values for motor with L = 3.6 mG and R = 1.8 om?And second question:Can ...

Working with the PowerStep01 and have run into a question regarding the minimum tick clock speed input. The documentation seems to indicate 4MHz but I can not find a min value.

The purpose of this is to determine if I can run the motor slower than approx. 15 steps/s which is the slowest possible with a 4 MHz tick. This is at the maximum microstep of 128. Considering a change to STSPIN220, lower current and voltage spec but ...

Monitoring ISB039V1.

Hi,We are researchers trying to use the ISB039V1T for an inductive charging application. In the past, we have worked with ISB045V1T and used the STWBC GUI with the STEVAL_WBCDNGV1 to flash firmware updates and monitor the board's charging status. How...
