Resolved! STP08DP05 resistor R-EXT current

Background:In our application STP08DP05XTTR is supposed to drive six LEDs with 20mA constant current each using an external, 1 k-Ohm output current programming resistor connected to the R-EXT pin (pin 15). The LED supply voltage is 5Vdc.Question: Doe...

sinusoidal PWM control for PMSM motor

Hi friends,   I am working in electric vechicle controller segment. Already, I have done my bldc controller using six step ( trapezoidal ) control method. I was completed my project using STM32f103c8t6 controller.  I need to control the PMSM motor us...

Is the stps5l60sfy footprint PSMC (TO-277A) too big?

We got this picture from our PCB manufacture. They claim there is "too much footprint" for this component and it causes sliding of the part. The footprint is made with reference to page 6 of this document. https://www.st.com/resource/en/datasheet/stp...

Signal sniffer

Hi everyone.I have a position encoder connected to a motor drive. The encoder transmit every 0.1ms a 73-bit data package using a protocol called EnDat 2.2 to the drive. The clock frequency is set to 5MHz, meaning one bit is 0.2 microsecond. Now I wan...
