How to I sync two SPV1040 solar charger ICs connected in parallel so that both of them have the exact voltage set point?
I am using 2 SPV1040 that are controlling 1 solar panel per chip. With that said, I am using a super cap with no battery and when the super cap is discharged the two ICs work in unison to charge the Super cap to the voltage set point. Once that is co...
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...
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...
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.
