I am really confused about driving mosfet. read many documents regarding this. some documents says gate current may be 2.5A, some says it may be 50mA.what is the actual formula to calculate gate current?I am using IRF510 (H bridge conf.) at 24V, 700 ...
Hello,I am working with STEVAL-SPIN3202 to develop motor control solution. I am using the Motor Control Workbench 6.2.1. I could generate the project using the workbench, however when i Connect the evaluation board, window with FAIL.txt opens which r...
Hi,cleaning out my drawers and found some 8-pin IC’s wirh the marking: ST CHN NESSSN K7U826 Does someone know what these do and have a data sheet?Thanks,Bas
We would like to inquire if there is a solenoid valve drive solution that can meet the following requirements:PWM frequency 0-5000Hz, current 0-3A , can superimpose dither signal 100-1000Hz, 0-600mA, dither waveform: sine wave and triangle wave
Hello! Hope your team is well and everything is fine!I'm currently using two stpm34 chips on a custom board connected in cascade to perform voltage and current measurements.Right now I'm performing measurements at a specific time through a timer inte...
Hi,I am using the STUSB4500QTR in my design.Pin 3 (in QFN package) is defined as NC.I saw that in some design examples it is connected to ground.Is it alright to connect it to GND or it should left disconnected?Regards.
Hi all, For the motor driver IC L6235Q the datasheet states it has overcurrent protection at 5.4A, can this value be changed to cut off the circuit at for example 3.0A? Thanks
STEVAL-C34KAT1 Vibrometer eval board came today and I see it came with 32 pin expansion flex cable (STEVAlL-FLTCB01). On one end, I plug it to this eval board. On the other, what do I plug it to? None of my ST eval boards have such connection. ...
Hi everybody,I made a circuit for the STPM34, but I keep destroying my components :)The first image is what my circuit looks like, I followed the datsheet closely, yet there seems to be a mistake somewhere.I've noticed it goes wrong at my current mea...
I am currently writing a driver for the STUSB4500L which has the ALERT pin (active low) connected to the MCU. An interrupt is triggered on a falling edge, and I then read the ALERT_STATUS_1 register. But somehow, the interrupt is not cleared. I then ...
