Hi,I am currently designing a PCB which has a number of TRIACs and photocouplers, to be used for switching mains on and off for some devices. For some reason, I have never before had to use TRIACs for professional products, but I know how they work. ...
I installed the power amplifier and replaced the TDA7388 with a TDA7850, but there's no sound after installation. What could be the reason?
Hi, Could you please provide MTBF/FIT values for M24512-DRMN3TP/K EEPROM? 90% confidence, 55C. FIT at activation energy (0.7 eV), if possible. Thank you.
Hi , i am trying to read the sensor data of AIS2120x only for sensor ID type , i can see from the bus the data is transferred correctly, but i don't receive any data back from sensor rather its only 0. i have attached the code snippet for this test, ...
Currently, we have developed a USB HUB Board.When we manufactured 5EA for the first time, it worked normally. (Current: 50mA)When we manufactured 10EA for the second time, 5EA worked normally, and 5EA had overcurrent. (Overcurrent: 450mA)After analyz...
Hello All, We planned to use STM Airbag IC- L9678P-S for one of our automotive application development. We intended to use L9678P-S having PSI5 /SPI/I2C sensor interface using Evaluation Board set up . Can some one share the Schematic of the EVB ...
