What is high side switching?
High-side switching is the preferred switching technique in situations where short circuits to ground are likelier to occur than short circuits to the positive power line. Think for instance of cars or machines where most of the structure or body is connected to ground.
What is a power switch IC?
The load switch IC is located between the power supply and the load. The ICs are used for power management to control the power supply to the load. Similar switches can be constructed with mechanical relays and semiconductors such as MOSFET, but load switch ICs can be miniaturized and consume less power.
What is low side power switch?
Low-side power switches are used to turn electrical loads ON and OFF by switching the GND (low-) side of the load supply. MOSFET low-side switches allow more control for applications that use high-speed pulse-width modulations (PWM).
What is high side and low side switching?
The low-side switch is switching ground while the high-side switch is connecting the voltage supply. Generally in a circuit, you want to keep the ground connected and switch the power.
Why are high side drivers used?
High-Side vs. The low-side driver is often used for powertrain-related loads such as motors, solenoids, and heaters. The high-side driver is used for fuel pumps, and body-related functions such as seats, lighting, wipers, and fans.
How do you choose between high side and low side switching?
So when you have a load that requires ground, you NEED to use a high-side switch. As a quick rule of thumb, if you are turning a device on and off, a low-side switch is a simple solution. However, if you are delivering power to an entire circuit or a voltage sensitive device, then you want to use a high-side switch.
How does switch IC work?
Analog switch integrated chips (ICs), when turned on, will conduct both analog and digital signals from the input pin to the output pin. When the digital switch is turned off, it returns to a default logic state. The long version. An analog switch acts like a solid-state relay (i.e., with no moving parts).
What is high side and low side drivers?
High-Side vs. A low-side driver is placed between the load and ground, whereas a high-side driver, shown in 2(b), is placed between the load and the supply voltage. The low-side driver is often used for powertrain-related loads such as motors, solenoids, and heaters.
What is high side and low side switch?
The low-side switch is switching ground while the high-side switch is connecting the voltage supply. Generally in a circuit, you want to keep the ground connected and switch the power. One reason is that even when the transistor is fully turned on, there is still a small voltage drop across it.
What are NXP smart high side switches used for?
NXP smart high side switches for automotive (12 V), bus/truck (24V) and industrial application are eXtreme switch devices. They belong to an expanding family designed to control, protect and diagnose various types of loads with enhanced precision in BCM, ECU or junction boxes.
Which is high side switch for industrial use?
The well-established high-side switch Industrial PROFET™ products were designed for targeting a variety of industrial applications which include all types of resistive, inductive and capacitive loads. Due to their outstanding energy robustness, they are perfectly suitable for switching even higher inductive loads and driving relays.
What’s the voltage range of smart low side and high side switches?
Smart Low-Side and High-Side Switches come with switch of all kinds of loads. They have a wide voltage range from 8V up to 18V in low-side switches. High-side switches fit perfectly for automotive applications based on 12V like power distribution, body control modules and heating systems.
Which is the smart high side power controller?
SPOC™+2 is the new generation of multichannel smart high-side power controllers for automotive and industrial applications based on SMART7 technology.
