Resolved! L6472 output voltage detected on motor supply
Hello, I have a board based on the stepper driver L6472. I noticed that, when I do not provide input 12V for the motor (the motor 12V but I provide the 3.3V for the logic (VREG, VDD, SW), I find a voltage of about 2.6V on the VSA, VSB pins. I tr...
E-L9823013TR
Hello!I would like to clarify, can I use octal low-side driver E-L9823013TR in daisy chain SPI configuration?Regards, Val
Alternative of LDFM50DT-TR LDO
Hi, In my current design, I am using LDFM50DT-TR LDO for 5V output which acts as a source for RFID transceiver circuitry. LDFM50DT-TR is preceded by MEV3S0505SC (Digikey link) whose output goes to LDFM50DT-TR, please check the attached image for more...
Resolved! Transistor configuration for a heating mat (big load)
Hello everybody, I am currently designing a configuration utilizing two drivers to heat a mat, which is a resistor load requiring 24V and 3.3A. This component is commuted at 100 Hz. For this setup, I've employed two different drivers: the first one b...
stpmic1 enter to unknown state when the board is powered with a specific ramp and is unable to power up
Hello,we are making qualification stress tests on our custom STM32MP157 board. One part of these tests consist to power the board with custom ramps that simulate the worst power scenarios (as glitches, slow ramp, brownout and blackout).We use the P/N...
spice model for STN4NF20L pin ordering
Looking at the ST spice model for STN4NF20L i see only .SUBCKT STN4NF20L 1 2 3 There is no text note in the spice model file as to what the assumed pin ordering may be. The nodes in the model have no helpful names like DRAIN GATE SOURCE. Yes I can f...
Braking mode with Low-side FETs bias ON with STDRIVE101 in standby.
Hi Motor Hardware Guru's,I am contemplating adding a mode that holds the low-side FETs ON when the motor drive is idle (sometimes for months) Is there a mode whereby GLSx / low side FET outputs can be set to high or high impedance state in standby o...
3 core flexible / rubber cable
Hi, I am looking for some very flexible 3 core cable for my soldering iron. The stock one on the soldering is very rigged. Heat proof and all that good stuff, tangle free as well. Thank you
L4986A model for Simplis/Simetrix compatible for POP Analysis
I am working on a project using L4986A. I was trying to get a bode plot of a boost PFC using L4986A model on simplis but I could not do a Periodic Operating Point (POP) analysis due to the IC containing non-linear blocks.I am wondering if there is a ...
