Dear Community,I'm a repair technician and I trying to identify a damaged component made by STMicroelectronics.Based on the surronding components and circuitry its a PMIC/DC-DC Coverter but I cannot find this specifc one.As you can see, all the infor...
In EVAL-L9963E-MCU evaluation board manual,the term 'VTREG' is refered to on many pages in word.But schematic diagrams or figures don't use 'VTREG' like the image attached below.What's the VTREG?
Triac snubberless (bta-16-800bw) does not require a snubber in the circuit?Or would installing a snubber in the circuit have a good effect?The difference between BTA16-800BW and CW is the gate current difference.Will the current specification selecti...
We are currently using the ST1PS02BQTR for powering a compact main board with BT connectivity (STM32WB5MMG), an IMU, and other ancillary blocks (LEDs, charge pump for LEDs, passives). The system is powered through two AAA batteries connected in serie...
Hello everyone, to simulate wireless charging of a smartphone (I want to achieve 5W transmission to the load), I need to use an electronic load and add the load step by step. Since the wireless charging system cannot immediately absorb high current, ...
Hello, I have designed and assembled a SMPS based on the EVAL-STCH03-45W evaluation board. What I have noticed, is that the power supply is outputting 1 Hz pulses with short buzzing sounds. These symptoms usually mean the hiccup mode is activated. Ho...
I am evaluating a PFC with the EVL4986-350W evaluation board.To be able to use Boost coils without the extra winding I want to supply the VCC voltage from a buck converter connected to the output voltage. The voltage from the buck is 17V.I have tried...
I have a PowerSTEP01 that is behaving unexpectedly when I send the ResetDevice command.If I send it when my system starts then everything is ok when I check the STATUS register.However, if I send ResetDevice after the motor has been moved (sequence e...
Dear allI use an STEVAL-ISV019V1 (Boost Mode) with a KXOB25-05X3F PV cell.When I connect a 330mF supercap to BATT, working at low light (200Lux) Store is being charged withing 30s. Not the SPV1050 tries to switch to the Supercap and restarts because ...
Hi everyone, I'm just starting in this field and I'm designing my first product. I'm designing a device that will use the L293D microchip and I'd like clarification on the following issues:1) There is a maximum value for the high voltage input curren...
