Hello, we are using the RHFL7913A to provide a negative supply for operational amplifiers. When we first supply the positive voltage to the op-amps, there is a positive voltage at the output of the RHFL7913A that is clamped to 0.4V by a protection di...
Hi, For a project I'm working on, I need to design a 3.3V power source (to power a microcontroller and measure circuit), the max load should be about 100mW. I only have a voltage source around 1000V next to it and I have to use it to make the 3.3V vo...
STPM32's document DS10272 states that Vref is 1.18V.However, if you install the "STPM3x Evaluation Software" program provided by ST and select the EVAL-STPM32 board in Configuration, Vref is set to 1.2V.which value is correct?In addition, if you look...
We are going to rotate the BLDC motor at a speed of 200,000 RPM.Is step-spin3204 possible?
My device has various connected sensors and peripherals. The device is intended to go to sleep for extended periods of time before waking up and taking measurements. Currently, the main VDD is a large external battery and VBAT is a coin cell used to ...
I use L6470 in my application at a certain running current. When I vary the speed the motor current remains more or less constant as expected. As soon as I change (actually increase) the MIN_SPEED value, the motor current changes (decreses). Anyone k...
My team has designed a circuit board based on EVSPIN32F0251S1 and controlled by the "STSW-SPIN32F0251" firmware, using the configuration "6step_conf_sl_cm_spdlp.h". The motor is moving fine, but during some measurements, we found strong current peaks...
I'm using the Software library "STSW-STUSB003" to configure STUSB4500 PDOs,I use the STEVAL-ISC005V1 with the stm32F072RB. my program works, I manage to modify the PDOs to get the desired voltage.But when the evaluation kit is disconnected, it revert...
Hi all!I can't find the parts by their markings. Help me please identify this SMD details:
