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
connected to V
IN
remains disconnected from the load.
