pmosfet

the pmosfet is used as a high‑side switch in many power‑management circuits.

in this design, the pmosfet gate is driven by a logic‑level signal.

the pmosfet exhibits low on‑resistance when fully enhanced.

you should bias the pmosfet source terminal at the supply voltage.

the pmosfet’s body diode provides a freewheeling path during motor shutdown.

when the pmosfet is off, its leakage current remains in the microamp range.

the pmosfet’s threshold voltage determines the minimum gate‑source voltage needed for conduction.

this board uses a pmosfet to isolate the battery from the load during charging.

the pmosfet can be modeled as a voltage‑controlled resistor in spice simulations.

proper heat sinking is essential to keep the pmosfet junction temperature within limits.

the pmosfet is often preferred over an n‑channel mosfet for high‑side switching because of its simpler drive.

in the datasheet, the pmosfet’s transfer characteristic curves show id versus vgs.
