I am driving a mosfet as a switch using GPIO pin of atmega328 running off 2AA cells. The circuit is logically similar to this http://www.electronics-tutorials.ws/transistor/tran59.gif
I ve tried BS250P however the load is not totally switched on probably because the mosfet's Vgs is too high and the AA cells voltage is less to drive the gate. Can you please suggest some other P-channel mosfet that are easily available.
Thanks and Regards, WonderfulIOT
