Hello everyone,My apologies if this is in the wrong forum. I have a STEVAL-BMS114TX evaluation board and I'm wondering what to do with unmounted cells, since my pack is 5s. The datasheet for the L99BM114 says to short the unused PCB connectors togeth...
Hii everyone,I am designing AC-DC board using STNRG012 IC and used EVL012LED evaluation board for reference purpose and we are facing some isuess1. We design input voltage range from 90-305VAC.2. PFC boost voltage range would be 450V.so which par...
Hello,I am evaluating the VND5T100AJ-E for an automotive application where I need to drive a 24V contactor. My design requirement is i need to drive the IC through the PWM signal as input.I have reviewed the datasheet but do not see explicit PWM freq...
good morning!Where can I get information about the datacode of such a chip ST1L05CPU33R?There is no information about the marking in the technical documentation.
Could you provide technical details or reference designs for a 2W wireless charger based on the STWBC86JR?
We are evaluating the L9916 IC and need to test it with different settings. We are following the information in the Datasheet and the Programming App Note. We keep the IGN, PHASE and LAMP pins at 0V right until the moment we send the ignition sequenc...
Planning L4981B as PFC controller as pre-stage to our DC-DC Convertor.Will this controller work with 400Hz can it be able to maintain unity power factor in 400Hz line as it does for 50/60Hz?Any other PFC controller recommendations will be appreciated
I am designing a LED driver board for an industrial instrument and am evaluating the ST1CC40 as a constant-current buck driver for the following application: Application requirements:• Input voltage: 5V DC (regulated)• LED: Cree XLamp XP-L2 white LED...
Hello,I used the SPV1050 chip to connect the circuit to the STEVAL-ISV019V1 evaluation board, and measured VSTORE to be 3.9V, which did not reach VEOC and naturally did not have LDO2 output. I use the STORE pin to power my sensor node load. May I ask...
Dear STM Team,Greetings!!I am writing to request you to please support in my PCB design review, as attached.I made a prototype board based on the simulation result for my 48V to 12V20A DCDC Converter requirement by using the e-design suite platform.K...
