Low Side Switching: Precise Control and High Performance Conversion
Low-side switches play an important role in electronic systems for precise control of current paths, especially for applications requiring high-performance switching. Low-voltage side switch series products with its low on-resistance, fast response and high integration and other characteristics, become consumer electronics, industrial control and automotive electronics and other fields of ideal choice.

The core advantage of the low-voltage side switch is its precise current control capability. The current limit threshold can be easily set via an external resistor, giving designers the flexibility to adjust the protection parameters according to different application requirements. This feature is particularly important in the USB port protection, battery-powered devices and portable electronics, can effectively prevent system damage due to short circuit or overload.

In terms of application areas, low-voltage side switches are widely used in:
Consumer electronics: power management for smartphones, tablets
Industrial control systems: PLC modules, sensor interface circuits
Automotive electronics: infotainment systems, body control modules
Networking equipment: power distribution systems for routers and switches

Load Switches: Intelligent Power Management and Inrush Current Control
Load switches play the role of ‘intelligent power gate’ in modern electronic systems, which can not only control power on/off, but also provide advanced functions such as inrush current suppression, power sequencing and status monitoring.

Another important feature of the load switch is its Quick Output Discharge (QOD) function. When the switch is disabled, the built-in 218Ω resistor quickly discharges the output capacitor, avoiding unknown states caused by providing floating power to downstream loads. This feature is particularly important in applications that require fast shutdown or frequent power switching, such as low-power mode management for portable devices.

High Side Switches: Reliability for Automotive Electronics and Industrial Applications
High-side switches are critical components in automotive electronics systems and industrial control equipment, providing reliable power distribution and protection in harsh environments.TI's line of automotive-grade certified high-voltage side switches features robust diagnostics and multiple protection mechanisms to meet the most demanding application requirements.

Application areas include:
Body control modules: door locks, windows, lighting system control
Automotive heating systems: seat heaters, tank heaters
Powertrain control: transmission control units
Infotainment systems: display power management
ADAS modules: power distribution for advanced driver assistance systems

Power Multiplexers: Flexible Power Management for Complex Systems
Power multiplexer is a modern electronic system to achieve power redundancy and seamless switching of key components, especially for the need for high reliability application scenarios. TI power multiplexer series products with its low conduction loss, fast switching and intelligent control features, become the communication equipment, industrial control systems and medical electronics and other fields of choice for solutions.

TI power multiplexer core advantage lies in its ability to automatically select the optimal power supply. When the system exists more than one input power supply (such as the main power supply, battery backup, supercapacitor, etc.), these devices can be based on preset priorities or real-time monitoring results, automatically switching to the most appropriate power input, to ensure that the system continues to operate stably. This feature is particularly important in base station equipment, data centres and medical equipment and other applications that do not allow power interruptions.
