Discuss power management solutions. Ask questions and find answers on voltage configurations, short circuit protection, and programming.
We would like to use the embedded STM32 in the SPIN for calculation purposes if no Vm power supply voltage is available.But datasheet is mentioning that Vdd < Vm. And the circuit diagram shows connections between Vdd, Vdda and internal 3.3V.Question ...
Datasheet, It is recommended to insert a capacitor between ADJ - Vo of RHFL7913 and RHFL4913. The capacitor value is 470 nF for RHFL7913. On the other hand, 47 nF is recommended for RHFL 4913. Does the value differ by one digit due to the difference ...
Hi everyone. I'm working on to drive 3 wheel omniwheel system for our project. I'm using parallel connection to have larger current. I realize that when i connect all the input and enable pins to ground (logic 0), all the leds connected to the outpu...
Hello to everyone. I'm making a 200W frequency converter for motor driving with APFC (~85...265 AC input) at my own 2-layers PCB and have some questions about influence from one half-bridge to another half-bridge inside the IC. Parts are driven in u...
Hi,I have Eval6229pd and I am having trouble in controlling of speed. It was controlling via arduino pwm. when vref is adjust there is no effect in terms of speed. So I was adjusting it by fwd/rev but the certain speed that I'd expect was not met. Is...
Hello,I'm trying to export the PSPICE model from eDesign Suite so I can embed it with our design in OrCAD. Is there a way to download the model from eDesign?
Well, I have posted a question in the eDesignSuite Q&A, but it seems to be the wrong place for it. Lets try here.I am looking for information about to feed the L4984D through self-supply. Does this controller works with self-supply or it is necessary...
Hey,i bought <nucleo-F401RE> and <x-NUCLEO-IHM03A1> boards in order to drive the NEMA 17 "QSH-4218-51" bipolar step motor. this one can be supply under 24V with 1A phase current. Using "BASETech-305" Volage Generator, i supplie the <x-NUCLEO-IHM03A1>...
Hello,I am using the STEVAL-SPIN3201 board to control a BLDC motor.I want to implement a position controller, so I need to hold tight the position of the rotor at a given position (1 phase to Gnd, 1 phase to pulsed Vm, and 1 floating phase).The probl...
We are working on Battery Status IC/drivers using STC3115 & purchased STEVAL-ISB014V2 from AVNET.Evaluated below drivers but still not working with Arduino also:https://github.com/st-sw/STC3115GenericDriver Changed i2c read/write, getting SLAVE ADDRE...
