WebThe LT1161 is a quad high-side gate driver allowing the use of low cost N-channel power MOSFETs for high-side switching applications. It has four independent switch channels, each containing a completely self-contained charge pump to fully enhance an N-channel MOSFET switch with no external components. Also included in each switch channel is a ... WebWhen using the MOSFET as a switch we can drive the MOSFET to turn “ON” faster or slower, or pass high or low currents. This ability to turn the power MOSFET “ON” and “OFF” allows …
WebThe term “power switch” (or “load switch”) is a general term. This document uses the term "cut-off switch” to describe a high-side discrete MOSFET power switch. Figure 1. Cut-Off Switch 2 The Discrete PMOS Cut-Off Switch The P-channel MOSFET (PMOS) is the simplest cut-off switch implementation, but there are two primary disadvantages.
