Timing Diagram
For example, if an application is specified to oper-
ate in 50°C environments, the PCB operates at
temperatures as high as 85°C. The application is
sealed and its PCB is small, causing R
approximately 120°C/W. Using Equation 2:

Dual-Input, Dual-Output Load Switch
To prevent thermal limiting, the operating load cur-
rent in the application must be less than 1.25A
which lies in the current limiting range. So, in this
application, any operating current below the cur-
rent limit threshold is allowed.
