STWLC33 NVRAM update
Hi,we're using STWLC33JRF in our design and recently we discover that we need to change some configurations trough the NVRAM. We've tried using ISB043v1 dongle to update the NVRAM but it won't detect the chip.We've also tried to write our own I2C dri...
Current rating per channel of VNQ5050AK-E?
Can I know what is the max current rating per channel of the smart FET VNQ5050AK-E, it is quad channel IC and its total current is internally limited to 19A.
I am using eval STPM34 for energy meter project. I am connecting ESP32 to STPM34 using UART. i.e. only Tx and Rx are used. I am writing ESP32 code using Arduino IDE. I cannot read any other register data
I am using eval STPM34 for energy meter project. I am connecting ESP32 to STPM34 using UART. i.e. only Tx and Rx are used.I am writing ESP32 code using Arduino IDE.When I use Serial2.read() function to read any register data, I always get "160 0 0 4"...
What can increase LM7915 ADJ-Pin current increase during start up?
During start up of a very simple LM7915 LDO within a split supply system for +/-15V sometimes ADJ-Pin Current increases during start up phase above the usal level.When this occurs, LM7915 can hang at 0V output voltage.As soon as adj pin current retur...
Step-by-step tutorial with example of calculations of the PFC integrated in the STCMB1
Greetings All,I would like a good example of calculations of the PFC intergarted into the STCMB1.So far, knowledge has been acquired about the LLC resonant. But not the PFC.Which chip is the closest ?Thank you.Best regardsSerge
Noise (click) problems while driving BLDC motor by using SPIN3202
Hi all, after many hours of tuning and trials I finally got my new BLDC motor running. It's a 36V, 180W rated power, Nominal current 6.8A.I am using FOC with 3 Hall sensors and single shunt. Problem I am facing is, quite often motor makes strange noi...
L6470 / L6472 VREG line question
Hello, I am designing the system with both L6470PD and L6472PD stepper drivers. Since my system is operating on 3.3V (MCU is STM32F103 ) I have tight the VReg with VDD line as suggested. The problem which I am facing is following. I supply the drive...
L6563 gate pulses happen only at the crest of Vac, for Vac>220Vrms and load <25%
Nice 3mSec string of gate pulses as Vac rounds the top of the AC wave, then the gate pulses stop for 5.3mSec until the next 60Hz crest comes along. Voltage waveforms on all the other pins look normal as expected. Schematic and complete set of scope s...
