I. ST Analogue Switches

ST analogue switches are low-loss switching devices specifically designed for the transmission and switching of continuous analogue signals. Their core function is the distortion-free switching and selection of multiple analogue voltage/current signals; they can transmit continuous waveform signals such as audio, sensor data and reference voltages. Unlike digital switches, which only transmit high and low logic levels, they are core components in analogue circuits and signal acquisition systems.

1. Key Technical Characteristics

ST analogue switches utilise a mature CMOS process, featuring extremely low on-resistance, minimal signal crosstalk and high linearity. They enable bidirectional signal transmission with no signal polarity restrictions. The devices support rail-to-rail signal transmission, with input signal amplitudes covering the full range of the supply voltage, effectively preventing signal clipping distortion. They also feature low off-state leakage current, high switching speed and low parasitic capacitance, thereby maximising the integrity of analogue signals and making them suitable for high-precision signal acquisition applications.

2. Mainstream Product Types

ST’s analogue switch product range is extensive, covering single-channel, dual-channel and multiplexer switches, including Single Pole Single Throw (SPST), Single Pole Double Throw (SPDT) and multi-channel selector configurations. Some models integrate overvoltage protection and electrostatic discharge (ESD) protection to enhance circuit stability. Classic series such as the TS series of general-purpose analogue switches and high-precision, low-distortion analogue multiplexers cater to varying requirements for precision and channel count.

3. Typical Application Scenarios

These are primarily used in scenarios demanding extremely high signal fidelity, such as industrial sensor signal switching, audio signal gating, high-precision ADC sampling channel switching, signal conditioning for instruments and meters, battery voltage detection, and programmable signal attenuation circuits.

II. ST Data/Signal Switches

ST data/signal switches are high-speed digital switching devices that focus on the switching, routing and isolation of digital signals and high-speed bus data. They are primarily designed for digital communications and high-speed data transmission applications. They recognise only high and low-level digital signals and do not support the transmission of continuous analogue signals, with their key features being high speed, low latency and high immunity to interference.

1. Key Technical Characteristics

Compared to analogue switches, ST data/signal switches are specifically optimised for high-speed transmission performance, featuring extremely low transmission latency, minimal signal jitter and high bandwidth, and supporting the transmission of high-frequency digital signals. The devices integrate impedance matching, signal buffering and electrostatic discharge (ESD) protection functions, effectively suppressing crosstalk and reflection issues during high-speed data transmission to ensure the stability and accuracy of data transfer. They also offer the advantages of low power consumption and compact size, making them suitable for portable electronic devices.

2. Main Product Types

The product range includes high-speed USB signal switches, HDMI video signal switches, I²C/SPI bus signal switches and general-purpose digital logic signal switches. These support multi-channel data switching and signal routing and distribution; certain models support hot-swap signal switching, meeting the requirements for live debugging of devices and interface multiplexing.

3. Typical Application Scenarios

Widely used in digital system scenarios such as interface multiplexing in consumer electronics, high-speed data transmission routing, switching of tablet and mobile phone peripherals, digital bus expansion for industrial control equipment, high-definition video signal switching, and signal gating for communication modules.

III. ST Power Load Switches

ST power load switches are specialised power switches designed for low-voltage power distribution and the control of low-power load supply. As power management devices, their core function is to control the on/off state of power paths, providing power-on, power-off and current-limiting protection for downstream loads. Primarily serving low-voltage, low-power supply scenarios, they are core components of power distribution systems.

1. Key Technical Features

ST power load switches integrate low-on-resistance MOSFETs, logic control circuits and comprehensive protection circuits, enabling power on/off control without the need for complex external circuitry. The devices feature fixed or adjustable overcurrent limits, short-circuit protection, over-temperature protection and reverse current protection; certain models also incorporate USB charging control logic, making them suitable for USB power supply applications. With extremely low on-state losses, they effectively reduce power transmission losses and support soft-start functionality to prevent inrush currents from damaging downstream load devices during power-up.

2. Main Product Types

The product range includes single-channel and dual-channel power distribution switches, covering three major categories: general-purpose, USB-specific and hot-swap-specific. Classic models such as the ST2052 power distribution switch are specifically designed for capacitive loads and short-circuit-prone conditions, and are suitable for various low-voltage power distribution scenarios. The devices feature compact packaging, making them suitable for high-density PCB layouts.

3. Typical Application Scenarios

Primarily used in scenarios such as USB host power supply, power distribution for portable devices, hot-swap power supply for circuit boards, power-on control for low-voltage modules, protection of battery-powered loads, and power distribution for low-power industrial control loads. These products focus on addressing safety protection and intelligent on/off control in low-voltage power supply applications.

IV. ST Power Switches (Intelligent Power Switches – IPS)

ST Power Switches, also known as Intelligent Power Switches (IPS), are high-power drive devices developed based on ST’s proprietary VIPower vertical intelligent power technology. Positioned above power load switches, they are designed for medium-to-high voltage, high current and complex load driving applications. Capable of directly driving various high-power resistive, inductive and capacitive loads, they are widely used in high-reliability applications such as automotive electronics and industrial control.

1. Core Technical Features

ST’s Intelligent Power Switch integrates a power MOSFET, driver circuit, logic control, diagnostic protection and fault feedback circuit onto a single chip, offering high integration and robust reliability. They are categorised into two main topologies: high-side and low-side switches. On-resistance spans a wide range from 4 mΩ to 300 mΩ, supporting operating voltages of up to 60 V and capable of sustaining high current output. The devices feature comprehensive protection against overcurrent, overheating, overvoltage and reverse breakdown, whilst also supporting fault diagnosis and feedback, enabling real-time reporting of load anomalies. They are suitable for demanding industrial and automotive applications.

2. Main Product Types

The product range covers single-channel, dual-channel and multi-channel intelligent power switches, including the OMNIFET low-side switches specifically designed for automotive applications, HSD high-side switches, and the IPS series of general-purpose intelligent power switches. Classic models such as the IPS160H and IPS161HFTR can meet the requirements for driving high-power loads across different current and voltage ratings, with some devices supporting high-frequency switching at 20 kHz.

3. Typical Application Scenarios

In the automotive sector, these are suited to vehicle body control modules, headlamp drivers, air conditioning temperature control, battery management, suspension systems and on-board power distribution boxes; in the industrial sector, they are used for DC motor drives, high-power relay control, industrial solenoid valve drives and resistive heating load control—all medium-to-high-power, high-reliability load drive scenarios.
