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...
Resolved! L6924D random status pin flicker in shutdown
Hello,i have a board with 10 L6924D on it, the schematic of each channel is derived from STEVAL-ISA076V1(*). Charging works as planned, CC/CV, correct max voltage and charge current and charge-end-current. Both status pins are connected to LEDs as on...
Does ST plan to ever make another Eval6235 board?
I hope this is an appropriate group. I don't see L6235Q anywhere. Is ST going to make any more Eval6235 boards? There doesn't seem to be any on earth. Choosing another controller is not an option. Mike

Resolved! Viper06 Buck mode converter, and AN4260
Hello, I need to be able to generate a small DC voltage from an AC voltage. The App Note 4260 looked absolutely perfect - exactly what I needed - 12V 150mA buck converter. Simple. no flyback transformers, etc. But I was a bit confused as to the GN...
Resolved! STUSB4761 vs STUSB4700 PD Source for compatibility with STUSB4500 PD Sink
Hi, I'm working on a board that has a USB PD input and a USB PD output.The board initialises via a generic PD 100W charger connected to the USB-C input, negotiating power for 20V / 5A via the STUSB4500. After this, I'm trying to source the voltage to...
