I am trying to produce a triac power controller for a large mains solenoid which is for a lab demonstration of electromagnetic induction. I have not had much success!My initial attempt used a simple 2-wire design as shown in figure 1 of ST's AN308 a...
Hi everyone, i am strugglig for a while trying to bring vn9e30f 24bit spi high side driver to life. Don't you know about any "sample" software which shows exact way how to change (for example on channel 0) duty cycle on given channel ? I tried almos...
HelloI want to use 3 x STSPIN220 for controlling 3 x stepper motors (motorized lens: Zoom, Iris, Focus). Currently to test lens I want with X-NUCLEO-IHM06A1 evaluation boards (with NUCLEO-F401RE). In stm32_nucleo_expansion_boards_motor_control_select...
Dear Sir/Madam,we are designing a PFC input stage for a power converter. High efficiency, low power loss, and low EMI (low dv/dt, low di/dt) are all important requirements. We have identified a suitable power topology for this stage: Zero-Voltage-T...
Hello,We want use sixpack SiC Power MOSFET module for drive a low power hi voltage motor.For safety reson I want measure the phase currents with 3 shunts connected beetween low side source and negative, instead one. With this package aren't avalable ...
Hi Community,I designed and developed a board for STUSB4500. I followed the schematic as mentioned in the STEVAL-ISC005V1 schematic diagrams, however I used only the main circuitry surrounding STUSB4500. There is no particular guidelines for layout, ...
I am using STWBC2-HP and STWLC99 for development. The output voltage at the receiver end is set to 10V, and the current limit at the transmitter end is set to 5A. However, the actual current at the transmitter end can only reach a maximum of 0.8A, an...
Hi.My project adopts stef01 chip for LED driver,I am meeting an odd phenomenon without thermal protection/overcurrent protection(I think),EN/Fault pin sometime is 1.4V,sometime it works well.It can be recurred when i rest the en/fault pin(efuse_rst=...
Hi, I bought the eval-l9963e-mcu, I want to know if I can use with SPC5 Studio, cause when i open the software and select L9963E it doesn't work. There is someone who already used this board?
Hello. I am reading the specification for L99DZ70XP and have some doubts about figure 3 in Section 2.4.1: There are two comparators in the figure used to monitor whether the ECV status is not reached/too high and input the comparison result into the ...
