I have a schematic with an ac dc converter flyback topology using the vipergan100 that deliver 100W as output power. i want to replace the secondary schottky diode with a mosfet to realise synchronous rectification but i don't know how to do this. th...
When using the external step input of the Powerstep01, will the internal logic also use the advanced fast decay mode and switch between micro and fullsteps if a given speed limit is reached?Or does the step input only count microsteps and not using a...
In the STPSIN software, it seems that I am limited to 15609.741 Steps / sec?(See picture below)With a 0.9 degree motor (400 steps / revolution)this limits me to15609 steps/sec * 1 rev/400 steps * 60 sec/1 minute = 2341 RPMIs this the maximum speed o...
Hello,just a short question: In Sensorless Mode the startup sequence works with "Align Step", where the Rotor starts from a fixed position. There is a define for the Motor Startup Angle (STARTING_ANGLE_DEG)... Is it relevant if there is 90 ° or 0 ° e...
Hello all,1) what is the recoverytime of the internal bootstrap diode from the mastergan4L2) why this diode need a parallel one for the frequencies above 500 KHzThanks for answeringGentleRV
I'm also waiting to see a response to this request. I've been scouring the ST website and have active support requests in to get firmware for the STEVAL-ISA172V2 boards that ST used to offer. I understand that in the future it looks like they will ...
Hello,i'm using some ips2050h-32 and ips1025h-32 from last year. Checking the datasheets, on the revision history they result been modified on july 2023, on table1, FLTx pins. Compared to the old version, seems that now it's been added the disclaimer...
Appreciate pointer to information. New to these. To power the STM32WL5EJC, we need to make a custom board incorporating the charging and protection circuit since 30mAh Li ion cell does not have build-in protection board.Appreciate circuit diagram, ...
I saw in X-CUBE-DPOWER that it is compatible with STEVAL-ISA172V3 with STM32G474RET6 in LQFP64.
