Doubts SPV1020, power optimizer

Hello, I am studying DC-DC converters, power optimizers for grid-connected PV.I saw some work with the SPV1020, but it seems to be discontinued. Do you know why? Is there a new version?I would also be grateful if I indicated any evaluation module, th...

Is there a way to default the STSpin840 motor driver to completely shut down the motor from turning upon power up?

I am currently using the X-NUCLEO-IHM15A1 Shield with the NUCLEO_F401RE MCU board to evaluate the use of the STSpin840 Motor driver using a single 12VDC motor. During the programming and debug process the motor will automatically start turning. Beca...

What do I connect pin 2 (VREFB) of the STSPIN840 to when I want to run the two outputs in parallel for higher current capability?

I am currently designing a PCB that will control a single motor using the STSPIN840 (X-NUCLEO-IHM15A1 Shield). The datasheet is pretty good about explaining how to connect things if you want to run the outputs in parallel mode but it neglets to tell...

Can I replace 5 ohm NTC from circuit of application note AN2097 ?

I am trying to replicate the circuit given in application note AN2097 which is a 10W SMPS at 12V.I am stuck 5 ohm NTC used in the circuit. Can you tell me the wattage of it. It is very expensive also, please tell me any way to replace it. Please find...

Anybody knows about the control of BLDC motor using two hall sensors and how to find out the exact mechanical angle between the hall sensors

We know that. when using three hall sensors, the 3 Hall sensors should be spaced across the printed-circuit board (PCB) so that they are 120° electrical degrees apart. From the center of the motor axis, the number of degrees each sensor should be spa...

6-step library not working

I'm trying to work with the STSW-SPIN3202 6-step firmware example for the Keil MDK, specifically the potentiometer example. I opened the firmware and in the infinite while loop I have MC_StartMotor() as per the instructions listed in there. But nothi...

Error in DS11245 Rev 3 datasheet Table 1 (LDL212)

Table 1, Pin description, on page 3 lists pin number 1 of DFN6 on GND row with a description of "Output voltage". It should be combined with pin #3 on Vout row.https://www.st.com/content/ccc/resource/technical/document/datasheet/group3/df/64/f9/b7/91...
