L7987L switch mode power supply battery charging application. My question will significant current from the battery flow into the L7987L when there is no input voltage but the input is open circuit?
L7987L switch mode power supply battery charging application. My plan is to have a rectifier followed by the L7987L buck-converter then a rechargeable battery. There is some protection provided by the Colomb counting current sense resistor.My questio...
Resolved! Problems with ST Motor Control and EVSPIN32F0601S3
HelloI am a beginner in the control of BLDC motors.I am trying to use the ST Motor Control program to control the motor but I have a problem.I have the EVSPIN32F0601S3 board.STM32CubeIDE cannot compile the program generated by ST Motor Control and th...
Oscillation on back EMF measurement using the STSPIN820 and a stepper motor
Dear community,Scope of the work: I'm trying to measure the back EMF of a stepper motor. I'm following the ST application note AN3327, which suggests that the back EMF is measured as the residual voltage on the coil when i_coil = 0. Problem: when mea...
Resolved! L6474 : behaviour of status register
Hi, starting from the documentation :"The UVLO, TH_WRN, TH_SD, OCD, NOTPERF_CMD and WRONG_CMD flags are latched: when the respective conditions make them active (low or high), they remain in that state until a GetStatus command is sent to the IC. "My...
Resolved! The leakage current of L6470H's ADCIN pin
Please see the attached picture. Our company is using L6470H chip for our design. According to the typical application in the datasheet, we want get 3V on the ADCIN pin. Our Vs is 24V and the voltage divider resistors that we chose are Ra= 13K and Rb...
