We’re currently facing an issue with the L4986A PFC controller in one of our designs. The IC is not functioning as expected, and we would appreciate your guidance.:wrench: Issue Summary:• The IC receives all input voltages within the recommended oper...
Hello,I'm in the process of moving from MP1 to MP2 on my device. The latter, used STPMIC1 that suffered the startup problem as described in AN5861 and I had to go thru a re-design to include the latching circuit on my PCBA.Can anybody confirm that th...
Hey everyone, I am trying to derive the internal gate resistance (R_Gint) of STP150N10F7. Can anyone help me with the calculation please. https://www.st.com/resource/en/datasheet/stp150n10f7.pdf Regards,Vamsi.
The calculation results from the power supply design tool and the values recommended in the Application Note are different. Is this okay?The device used is L5972DresultApplication note recommendationsOutput CapacitorPower Supply Design Tools 22μFAp...
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...
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...
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...
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...
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
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...
