I tried using a BS170 FET to supply / power-down sections of a circuit under
control of a PIC port pin.
The connections were:
Gate - port pin via 100R
Drain - to +5V
Source - to circuit to be supplied / depowered.
It didn't work! The FET appears not to turn on hard enough. Adding a pullup
to the gate did not help. The load being switched is in the low milliamps
range. Any suggestions as to a solution?
Thanks
