Resolved! Series resistor in VSPI pin of EV-VNF1048F
Hello,I was wondering why a 1K resistor is connected in series with the VSPI pin of the EV-VNF1048F.The pin has a current consumption of 3mA. So does that make a drop of 3V ?
Resolved! Charge pump circuit capacitor selection VNF1048F
Hello,I was checking the evaluvation board of VNF1048F for a efuse application to control motor drive. I wish to know how the capcitors for the charge pump selected in the evaluvation board. I am able to see 470nF in the evaluvation board schematics....
stepper motor stalling in deaccelerating phase in powerSTEP01
We are using the PowerSTEP01 driver in Current mode to drive the NEMA23 stepper motor.Supply voltage: 24V DC, Motor current 0.9A set in driver (motor max current is 2.1A)RPM Range 0 -1800 rpm; (0 - 6500 steps/sec)Acceleration / deceleration = 10000 ...
MASTERGAN4L Radiation Tolerance
I've been working with the MASTERGAN4L dev board to drive a transformer. This is for a purpose that will have to survive travel through deep space. I have a discretized roughly equivalent circuit made out of explicitly radiation tolerant / space rate...
STGAP2SiCSA
Hi,I am working with this driver for a full H-Bridge inverter application (DC-AC). My requirements exceed the current rating for the SiC MOSFETs I am using. I am planning on paralleling MOSFETs to meet the current requirements, so I would like to kno...
STCMB1 CONTROLL
I am designing a 200W 36V supply with STCMB1 driver, I am having problems with the circuit. The supply cannot supply the 6A of its capacity, it does not supply more than 800mA and the output voltage drops to 33V.
Problems setting up the STWLC38
Hello, We plan to use the STWLC38 for power in a new wearable design. We purchased the STEVAL-WLC38RX and STEVAL-WBC86TX kits to get familiar and experiment with the ICs. Now we are trying to adapt the Rx of the STEVAL-WLC38RX as used in a wearable d...
ALED1262ZT burn OTP I2C address
We've developed prototype board with 3 pcs AL1262ZT (https://www.st.com/en/power-management/aled1262zt.html). As a 'fresh device' it has 0x40 I2C address and it's need to specify unique addr (0x42, 0x44, 0x46) by burn OTP register. Our procedure: 1. ...
stwlc38 firmware download issues
We use wireless charger RX IC stwlc38, though we tried to write firmware which provided by the link https://github.com/STwirelesscharger/STWLC38_NUCLEO_L476RG, but we met the CUT id mismatch during firmware writing via I2C interface and then the F/W ...
STWLC38: GUI connect No response
Hello, I have a custom board with a STWLC38JRM. Everything was fine and I was able to flash it with STSW-WPSTUDIO v1.8.4 through the dev board STEVAL-WLC38RX and FT_SDA/FT_SCL/VBUS/AGND pins. I try to make some test and I disabled internal overtemper...
