Smart high-side switch
In plain English
What does Smart high-side switch mean?
A high-side switch controls the connection between a supply and the high side of a load.
A simple example
A controller can switch the positive supply path to an attached device using the selected component.
What the drawings help you do
Draw the switch between the positive supply and the load, with the return path shown separately. Identify any diagnostic output as a signal rather than another power connection. The word smart does not define a universal set of protection or diagnostic features.
- High side
- The supply-side connection of the selected load circuit.
- Diagnostic output
- A signal reporting a device condition for a controller to interpret.
Before using this reference
- Locate the switch on the supply side of the load.
- Label control and diagnostic signals separately.
- Reference the selected load, fault and thermal behaviour.
What makes this different from a low-side switch?
The location in the circuit differs. A high-side switch controls the supply-side path; a low-side switch controls the return-side path. Their drive and load-reference arrangements must match the selected circuit.

A distinction that matters
Monitoring and protection features depend on the chosen device, not merely the high-side position.
