Hi All,
We are using 12V magnetic coil in our project and switching on/off by linear led constant current regulator(bcr420uw6 ic). controlling bcr420u from micro -controller and current consumption of coil around 70mA
when i turn on magnetic coil the bcr420u ic heating up more after some time the going bad.
can any one suggest me how to solve the issue without heat or suggest me any alternate solution using different circuits.
below attached our application schematics.
Thanks,
Ashok
