What does a load switch do?

The basic function of a load switch is to connect and disconnect power to electrical devices in a circuit while also providing some protection. It acts like a protective electronic switch.

This product is most commonly used in mobile phones, computers, and IoT devices, where precise power management is crucial. Its greatest advantage is that it makes the system more robust and energy-efficient.

Key Features and Functions

The switch responds extremely quickly

Unlike ordinary switches that simply turn on and off, our load switches are controlled by electrical signals. They can operate autonomously, repeatedly turning on and off without issues, allowing chips or modules to receive power when needed.

Protecting Circuits and Components

Overcurrent Protection: If a load short circuits or excessive current flows, the switch immediately cuts off power, protecting the power supply and downstream devices from damage.

Overvoltage Protection: If the input voltage suddenly surges, the switch immediately shuts off, protecting delicate chips that cannot withstand high voltages.

Backflow Protection: Prevents reverse current flow, protecting components from damage.

Power Saving

When the device is in standby mode or certain modules are idle, it completely shuts down power, reducing power consumption to near zero. This reduces the power consumption of traditional LDO regulators in standby mode, naturally extending battery life.
