One of our project we are using L9369-tr IC and we are trying to communicate with the IC using TC38X controller with SPI protocol. We are able to send the data but IC is always giving 0x8efffff6 data as a response and it is not valid data. Could yo...
Can I find the manufacture year from the bulk ID? Most of ST parts only indicate the last digit of the year, sometimes we just don't know it is 2013 or 2023.
Hi, we are using L7987L IC top generate -15V from 24V input. However, we see repetitive failure in the IC. I have attached the waveform also (Green- Input Voltage, Pink- Vout). I am also sharing the layout for the same. Switching frequency we have ke...
I have a custom board that uses the L6470 for driving step motors. All motor functions are working fine. Circuit attached. Picture attached.What I have noticed and concerns me is that in instances where the motors are off or not even connected the ...
hello,I have STEVAL-DPS334C1 and STEVAL-DPSTPFC1. I am trying to put PFC code on STEVAL-DPS334C1 again. I load bin file via stm32programmer. then STEVAL-DPS334C1 crashes. I need source code to find where the error is coming from. Or if you have any s...
Hello.When I measure between 5V_SCR1 and GND_SCR2 in STEVAL-DPSTPFC1 Hardware, I see 9V. And when I start via Switch, it goes into standby mode when the output is unloaded and reaches 300V. It never becomes 400V. I quickly turn the switch to the off ...
Hello, This VN5E006ASPTR-E FET has unencrypted spice model? Thank you.
We use the VNHD7008AY to control the motor of a cargo lift. The lift has an emergency switch, which disconnects the battery from the circuit.In case of an emergency cutout, the lift runs down while its motor generates a high voltage, which finally ki...
Hi,I want to buy LDL212PUR LDO. I have 2 questions:1. Can it work reliably with ceramic capacitors?2. What are the recommended resistor values for voltage adjust version?I cannot find this information in the datasheet.Thanks,Adam
The TS3330AMR has a voltage reference, but the internal configuration of the IC is unclear.Is a reverse bypass diode, like the reverse voltage protection of a linear regulator, unnecessary?
