Looking for STWLC89 datasheet
Looking for datasheets for the STWBC2HP and STWLC89, do these exist? I can't find them anywhere on the internet
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...
EVALSTGAP2HDM
Hi, We have been testing our H-bridge on 2 EVALSTGAP2HDM with IPP026N10NF2S MOSFETs. The gate resistances are as per the EVAL board. We are seeing huge ringing on the gate signals for the low side FETs on both boards with no load connected. The high ...

I would like to identify the following two diodes, please.
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...
VN9D5D20FN: SPIE error when writing to specific bits in registers 0x01, 0x02, and 0x13 (SPI Mode 0, 1MHz)
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...
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...
ALTAIR04-900 switching frequency in burst mode
Hello! I am building a 50-600Vin flyback converter using the altair04-900 to power an LED as a student project. Due to the very light load I expect it to work in Burst mode. Currently I am looking for an adequate transformer. On this regards my quest...
