I am planning to use this N-Channel MOSFET for being switched ON/OFF by a Port Pin of the UNO. The load on the MOSFET is the UNO itself - so all together may not exceed 100 to 200mA.
the data sheet is here : http://www.farnell.com/datasheets/1648230.pdf?_ga=1.67044590.1144235018.1483419470
The MOSFET will be used in a kind of Push to ON latch application running off a 3.7V Lithium Ion cell.
The user pushes a key which fires the Gate of the MOSFET. The MOSFET in turn powers the UNO which then holds the gate at about 3.5V via a digital pin for about 10 seconds. The UNO does what it is supposed to do and then after 10 secs, the port pin drops to LOW switching off the MOSFET.
Will the MOSFET suit this requirement ?
