Can I have the reliability data for the part BU931P?
Hi all, I'm currently using the ST micro BU931P. I need reliability information on this part, life tests, thermal cycles, HAST, etc, the ESD level, MSL level, FIT and MTBF. Can you share these information with me?Thanks very much in advance for your ...
Selecting SPV1050 for energy harvesting from solar cell
Hi,This is John from Qmax Systems, We are designing a product - energy harvesting from solar cell. Our application requires a boost converter to convert 0.5V to 4.2V with an output current of min 100 mA. Do you think SPV1050 will support this applica...
Why isn't STM providing proper support for it's reference designs
Hi,Am a Designing enginner.I designed taking certain reference designs from ST.But when I posted certain questions regarding those designs I got the reply that there is no support offered at present for them and they directly closed the posted.I was ...
I want to know about error while loading program in STWBC-EP digital controller.
I have STEVAL-ISB044V1 board. I replaced new stwbc-ep digital controller. But board can't start to work. So i try to load program using command prompt and serial connection, but synchronization error is coming.What is solution of it ?
How to adjust driving current with STSPIN820
I use STSPIN820 to drive the stepper motor, which is noisy when it runs at low speed. I tried to reduce the supply voltage and the noise problem improved, but still could not meet the use scenario, although I reduced the voltage to the chip allowable...
Troubleshooting with spv1040 panel shunting
Hi!We developed a device using the SPV1040 as a DC-DC converter connected to the PV panel (5V MPPT 0.150A sc)When the no-load voltage of the panel is less than 2 volts, but the same panel when connected to the converter produces a much lower voltage....
Why do the output of the bridge rectifier shoot above 1KV when an inductor is placed as a filter in series with it?
Hi,I am designing an inverter using ST's application note AN2794.I have customized the application note which was designed for 1KW power to 1.65KW.The problem i am facing now is that when i probe the output of the bridge rectifier placed at the outpu...
Resolved! Always get STUSB4500 Not Detected message when using NVM GUI
I have checked and re-checked this. Also used another USB to I2C converter and can read the registers just fine. Put an I2C analyzer on the setup and I see no activity when the GUI program starts.Today on Github I found a HwCheckUtility.exe file. It ...
Resolved! two different IPS160H pinouts found
I am using IPS160H switch as a power switch input to DC/DC converters. But now I am confused to see a discrepancy between the data sheet and the STEVAL-IFP028V1 evaluation board schematics how to power the chip (Vcc). a) In IPS160H datasheet it says ...
