Chain STPM33 Clock
Hello,is it possible to cascade multible STPM33 Chips? That means SPTM33 + Crystal as master -> two STPM33 CLKIN-> Last CLKOUT -> two STPM33 CLKIN
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...
