Need a control electronic powered by an USB-C input which does provide 8V/1A output for a certain on-time after switching on the power of the board. After expiration of the timer the output shall be switched off again.
The time shall be defined by an resistor soldered to the board. It shall be possible to set the “on-time” from 30 seconds up to 360 seconds by means of changing the resistor on the board.
The electronic shall be realised as simple and low cost as possible and not involve any u-processor. Outer dimension requirements are defined, see attached drawings.
Looking for a schematic, the layout file, part list and 5 samples.
