We are using L7805CV , Input voltage = 30V output expected = 5V with 100mA of current requirement But we are getting 7.5V, the L7805 which is not correct,may know the reason?
We are using L7805CV ,Input voltage = 30V output expected = 5V with 100mA of current requirementBut we are getting 7.5V, the L7805may know the reason?according to datasheet input voltage is 35VCurrent supplied to the micro controller board and output...
Regarding STEVAL-SPIN3204
Purchased two (2) such boards (STEVAL-SPIN3204) from Digikey North America to evaluate the suitability of the SPIN32F0 for my automotive application.When attempting to download the eval software, I am trapped in an endless loop of "Error 403". In o...
STCS05, STCS1, STCS2 what is CDRAIN for? and will it operate without it?
The data sheets do not explain what CDRAIN is for. I suspect it is something to do with stability but do not want to use it because I need very fast PWM. Can these parts function without CDRAIN?
Fill area for PM8803
I am planning to replace a faulty PM8803 POE SMD. I have never dealt with pads and fill areas before, so apologies for what is probably an incredibly basic question.The layout guidelines say:"The exposed pad of the PM8803 must be connected to VSS: de...
What exactly is V_drop in the STP16DPPS05 datasheet?
I'm evaluating the use of STP16DPPS05 in my LED driving application.I'd like to drive two LEDs (wired in series) per channel at 5mA. The LEDs have a worst case forward voltage drop of 1.6V each. I intend to power the LEDs and the STP16DPPS05 with a 3...
Resolved! STP08DP05 resistor R-EXT current
Background:In our application STP08DP05XTTR is supposed to drive six LEDs with 20mA constant current each using an external, 1 k-Ohm output current programming resistor connected to the R-EXT pin (pin 15). The LED supply voltage is 5Vdc.Question: Doe...
sinusoidal PWM control for PMSM motor
Hi friends, I am working in electric vechicle controller segment. Already, I have done my bldc controller using six step ( trapezoidal ) control method. I was completed my project using STM32f103c8t6 controller. I need to control the PMSM motor us...
Is the stps5l60sfy footprint PSMC (TO-277A) too big?
We got this picture from our PCB manufacture. They claim there is "too much footprint" for this component and it causes sliding of the part. The footprint is made with reference to page 6 of this document. https://www.st.com/resource/en/datasheet/stp...
Nucleo Expansion Board Compatibility
Anyone know if the X-NUCLEO-IHM07M1 motor driver expansion board is compatible with the NUCLEO-F746ZG?
