Discuss power management solutions. Ask questions and find answers on voltage configurations, short circuit protection, and programming.
With zero load current, I'd expect the voltage drop between VCC and OUT to be essentially zero, since the on resistance is supposed to be 0.016 ohms (T = 25 C). Instead, there is a drop of 33 mV. VCC is 5 V. The datasheet lists a parameter of Von,...
The other info I struggle is on page 12 in the datasheet:CVDD higher than recommend values is allowed but external protection nets on VDD could be necessary for high VCC slew rate (>15 V/μs). In fact, we would like to use a bigger blocking capacitor ...
Hi all,I have a question about stspin220.h.There are two define as follow:/// Maximum frequency of the step clock frequency in Hz#define STSPIN220_MAX_STCK_FREQ (10000)/// Minimum frequency of the step clock frequency in Hz#define STSPIN220_MIN_S...
I am looking for any software folders related to the above eval kit. I cannot see any online and have requested such from regional support 10 days ago but still no files. If we do not get support soon we will have to move to another manufacturer due ...
Hi Sir/Madam,Greetings of the day,In my project I am implementing the AC-DC conversion circuitry to power the MCU and other external circuitry. So that I have taken STEVAL-ISA178V1 as reference. In that, it was mentioned that output current of the c...
We are to evaluating the L9916 (Multifunction alternator voltage regulator...). From the datasheet I learned that there are OTP registers which are programmed by I2C – as described in section “OTP Programming�? on page 30. Okay, but in addition we ne...
Hello , I'm using spin3201 motor control card. I downloaded example code in ST websites. Then i have uploaded the code as described. But i could not work potentiometer on card what i did. I read every user manuals in the websites. But i still could ...
I am making a GaN based boost converter. For the simulation work and real calculations i need the "forward recovery time of diode" .... specs of the diode is 100V,2A... please suggest best possible fast diode with mentioned forward recovery time.... ...
Hi Everyone: To drive the Three phase acim motor,I use stm32f401re nucleo to generate 6 chanel pwm and there are respectively three complementary wave to connect to Steval-ipm15b's control part.The 6 channel Pwm's period is 1000,and pulse is 500.Bu...
