An integrated load switch connects or disconnects a supply path under an enable or control signal.

## 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.

### 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.

### Terms

- Enable: A control requesting the selected device to operate.
- Output discharge: A separately specified feature that removes charge from a disabled output.

## How to read it

- Identify input supply and switched load output.
- Show enable control and any implemented status output.
- Reference startup, discharge and protection features individually.
- Startup control and fault-protection features vary by device; they must not be assumed from the block name.

## Information to show or reference

- Identify input supply and switched load output.
- Show enable control and any implemented status output.
- Reference startup, discharge and protection features individually.

## Important distinction

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