L6470 absolute position counter

Hi all,I have questions about L6470 absolute position counter:Can it be used reliably to count how many steps (or micro steps) the motor actually spins? For example, when at ABS_POS 0, if executing GoTo_DIR(1, 25600) (1/128 micro step mode), does it ...

BLDC simulink file and source code.

Hello~ I am program stm32f302r8 for bldc motor control. Does any ones has the file and source code like below? Luenberger state observer Rotor position estimation simulink file, source code for maximum torque per ampere, feed-forward current regulati...

Under what conditions can I achieve the specified efficiency with the LNBH29QTR (high efficiency typ. 93% @ 0.5 A). The STEVAL-CBL015V1 demo board is available. My attempts result in approximately 83%. Thank you very much.

STC3115 fuel gauge is not Working(NACK returned when I read the device id from master) and startup failed

Hello Everyone, We are having an issue with STC3115 (fuel gauge). We are connect Nrf51822(as Master) and stc3115 (as slave). we are read the device address from 0 to 127 . we got (I2C device found at address 0x70) from slave (stc3115) and...

Overcurrent with STSPIN32F0A. We have made replicated the eval board on our PCB and the same firmware presents as an error

Hello. I'm trying to find the switching losses for the IGBT "STGB30H60DFB". I found different Methods. Details in Detail-Window... Any help?

Switching losses:1. P = f * (Eon + Eoff) --> P = 32000 Hz * (383 uJ + 293uJ) = 21,632 W2. Pswon = 0,5 * Un * In * Füein * tr/T --> P = 0,5 * 325 V * 8,88 A * 1,2 * 14,6 ns / (1/32000 Hz) = 0,809 W Pswoff = 0,5 * Un * In * Füein * tr/T --> P = 0,5 ...

What maximum frequency can STPS20H100CT switch? How to calculate it from the datasheet?

Hello,I'm building DC-DC chopper that will switch at 80 kHz, max current of 8 A, how can i know if STPS20H100CT will be able to switch this frequency or not? It's not in datasheet.

Please give information about following electronics parts. ST VU M X GP 909 ST VU M X GP 836

I have made a circuit using ST1S14 IC and i am unable to get the desired result. I want Iout to be atleast 1A. Can you help?
