Dear ST Technical Support Team,We are encountering a blocking issue when running the eDesignSuite-generated reference code for STEVAL-7BIDIRCB. The specific workflow is:Power up the STM32G474 MCU firstApply 220V/50Hz AC inputProblem Description:The p...
I need to the FIT (failure in time) value for this part, 90% confidence level at 70 degree celsius.
Hi,I don't understand why VSNK stop after few second, do you have any idea ?
HI Sir,the switching frequency below input 24V 0.04A output 12Vis that normal. the switching frequency below, input 24V 0.01A output 12Vthe switching frequency below input 24V 0.33A output 12V the circuit see below:
Currently we use a PowerStep01 in StepClock configuration the current controller (CM_VM Bit set). Number of Microsteps is set to 2. Hold current (TVAL_HOLD) is set to 3 Ampere based on a 0.1 Ohm shunt resistor. All other registers are left on their ...
Our requirement was to create a LED driver circuit to power 12 strings of 7 LEDs from a 12V DC supply with a nominal current of 20mA per string.Using the STEVAL-ILL035V1 Development board data for PCB layout guidance and the LED7708 design tool sprea...
Hi everyone,I'm currently working on a project where I need to interface an STM32 with the L9963E BMS IC from ST. Before developing my own driver, I wanted to check if anyone has already written a C library for this IC and would be willing to share i...
BMS63EN connection problemI connected AEK-COM-ISOSPI1 and BMS63EN through PinMap provided by SPC5.However, I found two problems.1. When the input voltage is 56V, when I measured the voltage of Cell0, the voltage was measured as 10V~12V, and the volta...
Dear Madam/Sir,We are using powerStep01 and must implement motor "hardstop" purely in hardware (no software intervention).We consider these options:- using the external switch SW and bit SW-MODE = 0;- OR, with all voltages externally supplied, cut of...
Hello,LED1202 Can we use over 5V for VLED?For example, We plan to use 5V power supply. It's maximum voltage is 5.25V.It is my understanding that we can use maximum VLED voltage is VCS_MAX plus VF of used LED.Is that right?Thanks,
