sub. ref switch and an n-channel MOSFET as an Agnd switch, with a control circuit for controlling the signal applied to the gate of one of the devices (e.g., the n-channel device) to cause its ON resistance to match the ON resistance of the other device (e.g., the p-channel ...
A fourth n-channel MOSFET has a source terminal and a back-gate terminal connected to each other. A switch element is connected between the source terminal of the fourth n-channel MOSFET and a ground potential, and the source terminal of the fourth n-channel MOSFET is made become the ground...
The output voltage is defined as the voltage across the load, and therefore: V S + V OUT (eq. 1) A load switch is comprised of two main elements: the pass transistor and the on / off control block, as shown in Figure 1. In order for the N?channel MOSFET to turn on, the gate...
Most of these ICs on the market use external MOSFETs as switches for switching the current flow on and off, but also for limiting the current, in which case the switch works like a linear regulator. Such a switch must, however, ensure that the MOSFET is always operated within its safe op...

PURPOSE: To make it possible to block current regardless of the level of source and drain potentials, by using a bidirectional current blocking MOSFET not short-circuited with a p-body region with first and second N-regions that are connected to the ground. CONSTITUTION: A bidirectional current...
The PPC technique is implemented via power gating; it requires an additional transistor that acts as a switch to control the connection between the SRAM cell and the power supply. When the cell is in standby mode, these switches are turned off, effectively cutting off the supply and reducing ...
You may use any type of N-Channel MOSFET as long as they can handle the amount of current that your LED-strip requires per color channel. Design of the circuit board for the LED-strip Depending on your resources you can create your PCB as you want as long you follow the following schem...

The SPDT switch is used to select the H-bridge arm in the control direction. 3. H-bridge This is the working part of the circuit that controls the motor. MOSFET gates are usually pulled low by pull-down resistors. This causes both P-channel MOSFETs to open, but this is not a problem...
