Power Distribution Switches, Load Drivers, and the AP2181SG-13 Application Field and Working PrinciplePower distribution switches, or load drivers, are components used to control the power feeding into various components. Basically, power distribution is the process of controlling and distributing electrical power from the energy source to all of the connected components in an electronics system. Power distribution is a critically important process in electronics systems to ensure smooth operation of the system and to maximize battery life.Load drivers, or power switches, are components that use power transistors such as field-effect transistors (FETs) to control the flow of power between the power source and the connected components. Generally, transistors are used to control the magnitude and frequency of the power signals. Load drivers are often used in the process of switching the power between two points, since they are the most efficient way to do so while consuming the least amount of power.The AP2181SG-13 is a high-performance, cost-effective 8-channel load driver IC. It is a flexible motor drive IC providing load control and protection for applications such as brushed or brushless DC motors.
