-better to low-side switch with N-type devices
13
-
14
-Because N-type transistors in general can carry more current than P-types, they are preferable for switching heavy loads. Low-side switching with N-type devices is easier than high-side switching and can often be done by microcontroller ports without the need for special drivers.
15
-
16
-Using an N-type transistor for high-side switching is possible but requires a control voltage higher than the load voltage connected to the source/emitter. Some sort of charge pump is needed to pull the gate/base above the source/emitter voltage. This complicates the design, not only making it more expensive but also increasing its sensitivity to noise and interference. Controlling such a high-side switch using PWM can be problematic because of the charge pump.

-## high-side drive by P-mos
25
-
26
-To use a P-channel MOSFET (P-MOS), you should use it as a high-side switch.
27
-
28
-Explanation:
29
-
30
-- A P-MOS turns ON when its gate voltage is lower than its source voltage (typically, gate pulled to ground or a lower voltage).
31
-- In a high-side configuration, the source is connected to the positive supply (Vcc), and the drain connects to the load.
32
-- When you pull the gate low, the P-MOS conducts, allowing current to flow from Vcc through the load to ground.
33
-
34
-Low-side drive is typically used with N-channel MOSFETs, not P-channel.
