Viper UVP when configured as high-side buck
Hello,We are using Viper31 to step down 250VDC to 12VDC in a buck configuration as shown in Figure 42 of the datasheet:This is also the same topology used in STEVAL-VP319X1B:We are working with STEVAL-VP319X1B to try to implement the UVP function wit...
UM2458 Inverter (SPC560P50L3 + L6491D): No Gate Drive on MOSFETs
Hello ST community, I am working with the STM UM2458 inverter board (5 kW low-voltage, high-current inverter) using the STEVAL-CTM004V1 control board with SPC560P50L3 MCU. I am configuring the system in SPC5Studio, debugging with UDE STK, and using M...
VND5T016ASP-E High Side Driver IC Hardware Design
Hello everyone,I would like to use the VND5T016ASP-E high-side driver in my design.For one board, I need to use 12 of these ICs.I have reviewed the application note; in your opinion, which configuration should I use for this IC to have fewer EMC issu...
Resolved! L6920DB temperature range
The L6920DB temperature rating is not specified in the datasheet. However, it gives the temperature data as Max Tj=150C, Thermal resistance is 180C/W. Based on Tj=Ta+Pd*ThetaJa, if Ta=85C, then the Pd allowed in this temperature is very low. Is L6920...
Resolved! There is a prefix “A” added to the part number ESDA5WY
Hi Engineer, I purchased the part of ESDA5WY, and the type number showing on the label is 'AESDA5WY '. Could you suggest the meaning of the letter "A"? Thanks, Gloria
STEVAL-ISV019V1 High Battery Current
Hello!I am attempting to charge a 3.7 V Li-ion battery using the SPV1050 on the STEVAL-ISV019V1 evaluation board, but there is a current coming from the battery into VBATT which ranges from 400 uA to 1 mA.The current remains even when no load is conn...

Dear engineer Now, I want to get the LM2904's symbol to simulate in the PSPICE. AS usually , in this window，the symbol will be automaticlly created . but this time ,it does not be automaticlly created。Please help me solve ...
Resolved! STWLC38 will not report Ptx correctly
Hello, I am trying to follow the Getting started with the STEVAL-WLC38RX document for FOD tuning attached. I am using STEVAL-WBC86TX, powered from a bench top PSU, and STEVAL-WLC38RX, connected to an electronic load. Both are connected to the STMGUI...
Resolved! Powering Stm32f407vet6 from metal detector power supply
I have some Pulse induction metal detector analog designs that I want to "digitalize" using a Stm32f407vet6 board. Unfortunately, these designs use the battery positive as ground. My intention is to power the Stm32 from the +5v rail of the detector p...
Recommendations for a Flyback Design Challenge
We are in need of an Isolated Flyback DC/DC Converter design to work with a 24 to 96V battery system. It is to be a 15-140V input to 12V output voltage and, 4-5A nominal 9A peak output current converter. We want to use the Würth transformer "74919654...
