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...
No Output from EVALPWD13F60 board
We applied VCC1 & VCC2 @12V , VS = 110V, HIN1=3.3V, LIN2=3.3V (HIN2=GND & LIN1=GND) Measured output voltage across OUT1 & OUT2. However, no output voltage is observed. And also tried HIN2=3.3V, LIN1=3.3V (HIN1=GND & LIN2=GND). Here also same no outpu...
EVALPWD13F60 PWD13F60 only output pulses and not a permanent output
Hi Im using EVALPWD13F60VS = 100VVCC = 8VHINx and LINx = 3.3v GND = I connected the GND of my 100v supply, the microcontroller GND and the 8v supply GND.Output 1 to Output 2 = 5k resistor The problem that I'm facing is that I can only get pulses o...
We are using EVALPWD13F60. We are unable to make motor turn on.
We are using EVALPWD13F60. We are unable to make motor turn on. While we give pwm(10KHz) to HIN1 and LIN2 with different duty cycles by putting LIN1 and HIN2 as low , we getting 6 V as output. When we give HIN1 and LIN2 full time high voltage is drop...
