Power Switch ICs

Power switch integrated circuits (ICs) are electronic devices designed to make or break a power rail and limit another integral device’s power in circuits. They protect various circuits from short circuits, overloads, and high temperatures. They also provide low current leakage as they remain active when supplied with power. In addition, they are available in various current limit levels, such as fixed and adjustable, with standard package options that are crucial when choosing the power switch

Why are power switch ICs important?

These versatile switch ICs offer high efficiency, reduced cost, low power loss, better stability, and excellent reliability.

What are the different types of power switch ICs?

These power switch integrated circuits have been classified into the following types.

  • Low Side Switch

This switch type, where the transistor connects or sits between the ground and the load, is ideal for PWM-controlled load applications. 

  • High Side Switch

These switches sit or connect between the voltage source and the load’s positive terminals and are ideal for high-load applications. 

  • Current Limit Switch

As the name suggests, these switches limit the overcurrent supply and protect short circuits. They sense the current and detect whether the current does not exceed its predetermined limit. 

  • Load Switch

This high-side switch type sits between the load and the power supply in a series. These switches are best for conserving battery life by reducing system power consumption.

What are the typical uses of power switch ICs?

Power switch integrated circuits are standard in applications where power saving and protection are indispensable. They are also used in:

  • Automotives 
  • Communication Devices
  • Desktop Computers
  • Docking Stations
  • General Switching/Linear Applications
  • Smartphones
  • USB Ports

What are Intelligent Power Switches (IPS) and their uses?

Intelligent power switches are integrated circuits that integrate various actions into a single process designed to be used in automotive applications on a large scale. They are also ideal for use in smart home products and:

  • Agricultural Systems
  • CNC (Computer Numerical Control)  
  • Green Energy (Wind Turbines)
  • PAC (Programmable Automation Controller) 
  • PLC (Programmable Logic Controller)
  • Robotics 
  • Security Systems.
