Change PDO3 to 15V, 1.5A don't work
Hello Everybody, I'm new in this place. I use an Evalboard ISC005V1 with STUSB4500 and an dedicate MCU to manage I²C port. I wanted to change the configuration of the PDO3 from 20V to 15V. I select PORT3 ( write 3 in 0x70 register ) I configure DPM_R...
STEVAL-WBC86TX transmitter board locked — I²C reset not working
Hello ST community,I have two STEVAL-WBC86TX transmitter boards that appear to be locked. The boards still charge a phone when powered, but the I²C reset tool provided by ST cannot communicate with the main IC. I've tried FT260 recovery tool. I wo...

Resolved! STGSH50M120D pins K1 and K2
Hello,I want to adapt the STGSH50M120D to the circuit I already have working, but I have a question about pins K1 and K2. Will there be any problem with the STGSH50M120D if I don't use K1 and K2, leaving them disconnected?
STSPIN958 Thermal shutdown does not work
Hi,We are using STSPIN958 for BLDC control, and under 33V, 2A, when external force applies to servo, and the current goes up to about 2A, the chip burns before the thermal shut down kicks in.I would also like to know the value of "Tsd" delay timing p...

Dear ST Community and Experts, I am facing a persistent SPI error (SPIE bit set) issue with the VN9D5D20FN high-side driver and would appreciate your help in troubleshooting. 1. Problem Description: I am attempting to write to specific control regist...
VNH9030AQ footprint / land pattern?
Hello - I'm looking for a footprint or land pattern to use for designing a PCB around the VNH9030AQ. I'm sorry if I've overlooked it somewhere--can anyone point me in the right direction? Thank you for your time!
Strange High Side Switch behaviour / VN751PT
HI! We have from time to time defect High Side Driver. Most of the defects occur after the first few power on cycles. The High Side Driver and the RGND Resistor (120Ohm) gets really hot. The resistance between GND and the Status Pin is then much l...
