Integrated load switch
In plain English
What does Integrated load switch mean?
An integrated load switch connects or disconnects a supply path under an enable or control signal.
A simple example
A controller can turn a subsystem's supply on only when it is needed.
What the drawings help you do
Put supply input, switched output and enable control on separate labelled connections. The load switch turns a subsystem’s supply on or off. Soft-start, discharge and fault protection are optional product features; show them only when the chosen device provides them.
- Enable
- A control requesting the selected device to operate.
- Output discharge
- A separately specified feature that removes charge from a disabled output.
Before using this reference
- Identify input supply and switched load output.
- Show enable control and any implemented status output.
- Reference startup, discharge and protection features individually.
Is every load switch also an electronic fuse?
No. A load switch primarily controls a supply path. Current limiting or fault interruption must be explicitly supported by the selected product or separate protection circuit.

A distinction that matters
Startup control and fault-protection features vary by device; they must not be assumed from the block name.
