Resolved! diode identification
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...
Resolved! SPV1040 - using LX to generate a boost supply
This is to turn on MOSFETs that operate above 5.2V supply of the Boost regulator. I have followed a forward converter guidance roughly in one of the application notes, but I have not used a transformer but placed a high value resistor in the voltage...
Resolved! Wlc38 Digital Ping Power Consumption
Hello, We are looking to use the Wlc38 in Bi-directional mode alternating between RX and TX digital pings. We are wondering how much power consumption the digital ping takes and for what duration so we can calculate power consumption of pinging at va...
STWLC89 application related
Hi,Since we haven’t received the datasheet yet, we’d like to confirm the following information:If the receiver side (RX) uses the STWLC89 15 W solution, what is the corresponding 15 W transmitter (TX) model?Which Qi standards are supported by STWLC89...
Resolved! About High Side Driver Selection
Hello everyone,I am finding to drive for 4 cabin lock. For this, VNxxx or VNQxxx series help me. I don't need high current. It is 1 amper per channel(per output. I'm looking for a chip that will not cause any supply problems and will be produced con...
