Why is the power efficiency of the SPV1040 not matching the datasheet values?
Hi all,The application that I am building uses a rectenna to provide DC power to anSPV1040 which performs its MPPT algorithm and outputs the converted power to anattached load (VStorage). Here is how the SPV1040 is configured for ourapplication: The ...
Resolved! PowerSTEP01: Electrical constant of the motor (ke): clarification need for ST documentation: "Measure the peak voltage ..": What to measure exactly: Vpeak-to-peak, Vpp/2, Vmax or ... ???
In UM2022, Appendix C Motor electric constant (Ke) measurement written:"Measure the peak to the frequency ratio" (by oscilloscope).Our question: what voltage to measure EXACTLY ?:Vpeak-to-peak, Vmax, Vmid, etc ??I think it's fundamental to get the ri...
Resolved! What is the nest best replacement for the STPMIC1APQR?
I would like to start a project with the STM32MP157D microprocessor but cant find the power management chip due to supply issues and I do not know any suitable replacement.Thanks!
PM8803C asserts TP2 without 802.3at Type 2 sequence
I have a PM8803C which asserts the TP2 pin when it only sees a single classification event (vs 2 event for Type 2 per 802.3at standard). I believe a non-standard 2.3ms 6v pulses for 114ms delivered on power up triggers the PM8803C to assert TP2.Can a...
