Then we can summarise the switching characteristics of both the N-channel and P-channel type MOSFETS in the following table.
MOSFET Type | VGS (+ve) | VGS (0v) | VGS (-ve) |
N-channel Enhancement | ON | OFF | OFF |
N-channel Depletion | ON | ON | OFF |
P-channel Enhancement | OFF | OFF | ON |
P-channel Depletion | OFF | ON | ON |
Note that unlike the N-channel MOSFET whose gate terminal must be made more pos
Complementary MOSFET Motor Control Table
MOSFET 1 | MOSFET 2 | Motor Function |
OFF | OFF | Motor Stopped (OFF) |
ON | OFF | Motor Rotates Forward |
OFF | ON | Motor Rotates Reverse |
ON | ON | NOT ALLOWED |
How to use an N channel MOSFET (a type of transistor) to turn anything on and off! Also, remember to put a 100k resistor between gate and ground if you want your FET to stay off by default.
