when I use vl6810 with 51 chip , the i2c use pull up to 1.8V 。all the init register is correctly， I Using an oscilloscope for detection ，It seems all correct。but it always wait at VL6180X_REG_RESULT_INTERRUPT_STATUS_GPIO here ：while(!(VL6180X_Read...
Need to know:What is the material attached with the die to the lead frame for this microcircuits part STM811TW16F? gold wire bond or coper wire bond or other?
we are noticing some failure SPV1040 in our implementation on a board for energy harvesting from solar panel. The breakdown is only for SPV1040. Short between GND and Vout. Attached schematic for your reference.we have taken the reference design of S...
Hi,I am trying to figure out which TOL Sensor to use for a robot application.Usecase: Distance measurement on coated shiny metal surfaces while moving over them, to detect an edge. Detection Range 10-50mm (if it detects further that would be fine, bu...
We have a Load-Rite Pro LR918 loader scale. The device does not keep time anymore.You can set the time but it doesn't advance at a proper rate and usually within 1 week it is about 6 days behind. I opened up the scale main control unit hoping to find...
Hi, I can't find the ULN2804A with SMD SOC18 surface assembly, my question is,can I replace with the unl2803a SMD SOC18 ?n practice I have to repair an electronic card,I found all the components excluded the ULN2804A with surface assembly Soc18,which...
Need following documents 1) Visual inspection report2) X- ray report3) functional report
Dear ST Community, Currently using the M24C64-A125 as EEPROM. We have a performance challenge in which we need to write a certain amount of data in less than 100ms. We checked the datasheet and we found out that The Page Write mode allows up to 32 by...
I have designed a 24v SMPS(switch mode power supply), but it is restarting what is the reason for that, I have used viper38hd IC.Here I attached my schematic, ic datasheet, and transformer datasheet.
Hi I have a design with the STUSB4500 per the attached schematic snippet and programmed per the attached memory map. This circuit is on a tiny board inside the plug end of a captured USB cable. The PDO's are programmed to default to 20V @ 3A.The app...
