Il the decription of the datasheet we can read this text :They are designed for interfacing between electronic controls and power triacs to control resistive and inductive loads for 115 VAC operationsBut in the Typical Application Circuit (figure 12)...
Hi, I'm looking for technical help on an L7981 voltage regulator issue. We have been using these for years in various designs with minimal issue. On a recent new prototype, I am having an issue I have never seen before, where on occasion the regulato...
I have a motor control PCB with x6 L6472PD stepper motor drivers on. 2 of the drivers are being used to drive NEMA17 "hybrid stepper" linear actuators that move a module along a linear guide. The two drive systems are laid out identically, and conven...
My test reference circuit is from Mr. Christophe Basso's book: "Designing Control Loops for Linear and Switching Power Supplies By A Tutorial Guide"The picture is showed as follow.Unfortunately, it may be a problem with my test circuit, or maybe the ...
We have had 3 dates in the last month with different distributors where items have been shown as coming in and we have ordered; but when the date passes they become marked as 45 week lead.
I am trying to reset the power by controlling GPIO3.3V.However, the initial power is ON and OFF only, and there is no control thereafter.
We designed board with PoE capability using ST PM8800 chip. We encountered some problems.Issue #1When our board is powered from external power supply (Vin(AUXII)=32V) we get output voltage with high ripples and PM8800 nPGD is inactive (High). Ripple ...
hi I have the ihm08m1 how can I change from 1 shunt to 3 shunt if by default it is soldered on 1 shunt?
Hello,I use the EVAL6480 Board and the STM32 F446RE as MCU to communicate to the driver.My Steppermotor [1] (not exactly this but very similar) has oer phase a resistance of 1,2 ohm.My Problem is that the motor does not turn because the UVLO flag is ...
