High Side Power Switch

Figure 8 illustrates an application circuit for a logic con-

trolled high side power switch. When the CTL pin is a

logical low, the LTC4411 will turn on, supplying current to

the load. When the CTL pin is a logical high, the LTC4411

will turn off and deny power to the load. If the load is

powered from another (higher voltage) source, the supply
