A switch is used to connect and disconnect electric circuits at will. Switches cover a wide range of types, from subminiature up to industrial plant switching megawatts of power on high voltage supply and distribution lines.

In applications where multiple switching options are required, mechanical switches have long been replaced by electronic switching devices which can be automated and intelligently controlled.

A switch can also be referred to as a "gate". In the philosophy of logic, operational arguments are represented as logic gates. The use of electronic gates to function as a system of logical gates is the fundamental basis for the computer.

The MIC94065 is a high-side load switch designed for operation between 1.7V to 5.5V. The devices contain a low on-resistance P-channel MOSFET that supports over 2A of continuous current.

The MIC94065 provides a slew rate controlled Soft-Start turn-on of 115µs (typical) to prevent in-rush current from glitching supply rails.

The MIC94065 features an active load discharge circuit which insures capacitive loads retain no charge when the main switch is in an OFF state.

An active pull-down on the enable input keeps MIC94064/5 in a default OFF state until the EN pin is pulled to a high level. Built-in level shift circuitry allows low voltage logic signals to switch higher supply voltages, or vice versa; high level logic signals can control low level voltages.

The MIC94065’s operating voltage range makes them suitable for 1-cell Lithium ion and 2- to 3-cell NiMH/NiCad/Alkaline powered systems, as well as all 5V applications. Their low operating current of 2µA and low shutdown current of <1µA maximize battery life.

The MIC94065YC6 is a high side power switch with soft-start and load discharge functions that comes in a SC-70-6 package.
