Power management

Hi, is it possible to use X-NUCLEO-IHM03A1 with a Nucleo-144 board? Are they compatible? Regards, Giuseppe Reale

We are using L7805CV , Input voltage = 33V output expected = 5V with 20mA of current requirement But we are getting 7.5V, the L7805 may know the reason? according to datasheet input voltage is 35V

Current supplied to teh micro controller board alone,it is nowahere connected,Still 7805CV not able to deliver the 5VPlease find the attached circuit and let us know please let me know why this circuit is not working or let us know the input voltage ...

How to identify BLDC motor is rotating or in steady state using STEVAL-SPIN3202 board

We need to identify BLDC motor state(rotating or steady) when board power up. The issue i am facing is, BLDC motor stops with ****, due to initial init functions.Is there any way to identify that bldc motor in rotating state or steady state, from sof...

What is the maximum junction temperature of the LD56050?

The datasheet states an "Operating junction temperature range" of -40 to +85 degC in table 3. The thermal shutdown in table 6 is given as 160 degC. How do these two relate?

Setting up STEVAL-FCU001V1

Hi.I am a bit confused how to set up the STEVAL-FCU001V1 kit. Is there any kind of tutorial on how to load a firmware onto the board? I've got a STLINK-V3SET and a STLINK V2. Where do I have to connect the Powersupply and the SWDIO and SWCLK from the...

5V 1A power supply using ALTAIR04-900TR

i have made 2 pieces of 5V 1A power supply using ALTAIR04-900TR  as per the circuit design in eDesignSuite.Now as i power on one of them it blow the fuse and rectifier in AC input. i tested for any sort of short circuit but i did't find and again i ...

Voltage drop at motor input

Hi everyone. I'm new to motor control and have some problems with my robot. We are designing a three-wheeled omnidirectional robot which should bare and transport weights about 10 kg. We use Pololu 12V DC motors which has a stall torque of 8.5kg-cm....

Hi all, I would like to use a NUCLEO-F401RE with the expansion boards X-NUCLEO-IHM03A1 and X-NUCLEO-IHM02A1. Is it possible to use these two different expansion boards at the same time with the same NUCLEO board?

In particular I have to control 3 stepper motors (24V, 9A) with 3 X-NUCLEO-IHM03A1 and 5 stepper motors (24V, 2A) with 3 X-NUCLEO-IHM02A1.

L6566B reset indicating shorted

We designed an AC / DC power supply with the L6566B with the help of the eDesign tool. We manufacture a 5-piece pilot lot and are encountering a problem with two parts that do not start the L6566B.Taking some measurements we realize that at pin 5 (VC...
