Load Switches: What Are They, Why Do You Need Them And How Do You Choose The Right One? 1. The pass FET is the main component of the load switch, which determines the maximum input voltage and maximum load current the load switch can handle. The on …

Solve your design challenges with our broad portfolio of load switches which includes extensive current, package and timing options. These devices are a simple, cost effective way to turn on and off your power rails.

What is a load switch? Extend battery life by reducing standby leakage current. Turn off unused subsystems w/load switches: WiFi/BT, LCD, SD Card. Simplify power sequencing by implementing point of load control with load switches. Power on/off each rail with GPIO.

What is a Load Switch? A load switch is an electronic component that has no moving parts, which works somewhat like a relay. Generally, two MOSFET transistors act like a switching element, one of them being an N-channel device, and the other a P-channel device.

2018年7月25日 · Load switches are all-electronic, easily controlled ICs which allow a circuit to turn DC power rails on and off, and also offer additional features beyond that simple function.

Before selecting a load switch, let’s go over some basics of load switch functionality and performance. Basically, a high-side load switch connects or disconnects a power source to a load and the switch is controlled by an external enable signal (either analog or digital).

The load switch is an insertion into the power path between the source and load. Therefore, it is important to understand what this insertion can impact the device’s performance. The fist step is to know the voltage drop caused by the ON-state resistance of the pass MOSFET.

High-side load switches are highly integrated power switches used to connect and disconnect a power source from a load. Using a load switch instead of a regular MOSFET offers several features including simplified design, small footprint, and protection features.

This FAQ will examine issues related to high-side and low-side power switching and control via load switches and the implications when choosing and using each type. It will also look briefly at the load switches that are used.

A load switch IC is a semiconductor switch inserted in series between a power supply and a load circuit or IC. The use of load switch ICs simplifies: 1) the supplying of power to each system block, 2) power supply sequencing for ICs, and 3) circuit protection from system failure.
