Dear communityI have developed a bldc motor driver using a DRV10983 chip from texas instruments target speed 3000.00 RPMIt works of BEMF and dose not use hall effect sensorsI have achieved good stability but the instrument the motor is designed for n...

LT-Spice Model L5973D

Dear Sir or Madam,we use the DC-DC Converter L5973D in some circuits and i want use it in the future, too. To do it easier I prove the circuit with a LT-Spice based programm.Now my problem is, that your offer a encrypted Pspice-Model. It is possible ...

Used eDesignSuite to design an isolated AC to DC Flyback converter circuit for wide voltage AC input, and 5V, 0.8A DC output.

The eDesignSuite result and my schematic are attached. A PCB was manufactured as per the eDesignSuite BOM and design guidelines. I connected mains to the circuit without SJ4 being bridged. Rin immediately blew. The design BOM specified a 7.5Ω , 2W re...

STEVAL-SPIN3201 and MATLAB/SIMULINK

Hi,[1] Is this board supported for automatic code generation in MATLAB/SIMULINK ? [2] How high must the electrical rotary field resolution be for FOC operation, if I want to operate the PMSM without an observer? [3] Is it possible to switch the opera...

Would like to use STNRGPF01 Digital Controller for a system with 480 VAC input. The AC input voltage sensing is isolated, is there a reason this can't be used at 480 VAC?

When trying to set up a simulation in E-Design, the highest input voltage that can be input is 265?If this can be used at 480 VAC as I suspect, how do I get the voltage settings on the E-desgn tool revised

STUSB4500, how we can set profile through I2C using nrf52832 MCU.

Hello, I am using STUSB4500 Type C IC , I want to set the profile for 5V 3A.I referred the code given in Github:https://github.com/usb-c/STUSB4500Same we have implemented in nrf52832 SDK, but its not getting programmed.Any solution for this? How we ...

VNH7100AS pull down resistor

Hello, do the INA INB and PWM pins have an internal pull down resistor?In the examples you connect these pins with a 1k resistor directly to the microcontroller, but if you do not have a pull down resistor you may be fluctuating at the start of the m...
