Resolved! L7987 switching frequency
HI Sir,how do we define the switching frequency of the L7987the switching frequency range is between 250KHz and 1.5MHzlooks like if the switching frequency is set to 1.5MHz, the ripple appears to be much smaller, so can we set it to 1.5MHz under norm...
Confused about stepper spec & tips on pwm-step/dir
Hello! I have asked the few I know who have knowledge of this and now turn to this one inexhaustible source of knowledge aka. the electronics forum. I was going to buy stepper motors yesterday but got so confused about the spec that I need to get an...
please reply my question regarding L9396 and WSS PWM Data
Hello. I am using L9396 for WSSWhen reviewing the WSS operation with the ST_L9369 datasheet, there is no detailed explanation regarding the Pwm Data format DATA[0...8]. Could you provide information on what each bit represents?
LED1202 (QFN20) Thermal resistance(janction to ambient) except for JEDEC PCB(2S2P)
Hello, We are making a design LED1202 (QFN20) and need thermal resistance(janction to ambient). What is the thermal resistance (junction to ambient) except for the JEDEC PCB(2S2P). We use smaller copper area of printed circuit board or less layer th...
STEVAL-IP023 firmware update with STM32CubeProgrammer fail
I tried to update the STEVAL-IP023 board with DFU using STM32CubeProgrammer, but the STM32CubeProgrammer hang during the procedure, see picture attached.The board is recognized ad DFU device but the procedure does not work.Any suggestion?Thanks
STGF7NB60SL IGBT Material Properties
Dear STM,I am a student and currently working on the lifetime estimation of an IGBT for my research, which involves a Finite-Element simulation on STGF7NB60SL IGBT.To run the simulation, I need to know the material properties of different layers in t...
