Resolved! What causes L6472 to power up / leave reset with bridges active?
I have designed a board with four seemingly identical motor drivers. The four L6472 are connected to an STM32-MCU via one SPI-interface, chipselect is handled by GPIO. They share a common reset signal, also GPIO. Because of the pull-downs on /STBY_RE...
Gate driver for STY139N65M5
Hello,Has anyone used the 650V MOSFET STY139N65M5 in any of their designs? If, yes what was the operating frequency and the gate driver used in this case.Thanks,Mausamjeet
do you have software release plan of STWBC2 & STWLC88?
want to know software release plan or not.
Resolved! SMAJ Peak Pulse Power over Pulse Duration Curve
How is the curve in Figure 4 in the datasheet measured? I noticed in Figure 5 that the 20 us pulse has a 8 us rise time and the 1000 us pulse has a 10 us rise time. The 10 ms pulse doesn't even have a specified rise time. Is each point in the Figure ...
STSPIN220 Microstepping
I currently am running a stepper motor with a STSPIN220. I wanted to configure the STSPIN220 into 1/8 step mode, but I cannot decipher what I need to do to configure the microcontroller to send out the proper command to set the STSPIN220 into 1/8 ste...
Looking for a motor driver IC VNH3SP30-E
Hi,For one of my new design we are planning to use VNH3SP30-E but con't able to get anywhere from online. Every one have a lead time of 52Weeks. How can i purchase this IC or any other equivalent to replace this? Awaiting for your feedback.Thanks in ...
STCMB1 controller
Does anyone know the power rating for the internal fet on the discharge pin 8? I need to use a 50 uf 5 volt cap due to long ramp time requirement on Soft Start and my concern is to exceed the energy rating of this internal device during the dischar...
L7987L switching regulator, does not output expected voltage
I am testing the L7987L chip for my PoE module project. I got the dev board STEVAL-ISA198V1.I noticed that it gives out 4.8V instead of 5V (with or without load). Also I was expecting that chip will cut output once the input voltage is less than 5V (...
