Optoisolators are electronic components that provide electrical isolation between two circuits. They are also known as optocouplers, photocouplers, or photocouplers. The 4N28SVM is an optoisolator designed specifically for motor control applications, providing solid-state drive and feedback coupling. It offers high levels of electrical isolation between the drive and feedback circuits by using an infrared light-emitting diode, (LED) and a photovoltaic-output transistor.

4N28SVM Application Field

4N28SVM optoisolators are ideally suited for motor control applications requiring solid-state drive and feedback coupling. It provides isolated feedback control in applications that use pulse-width modulation (PWM) for motor speed control. The 4N28SVM is also suitable for motor control and temperature controls requiring isolated signal monitoring.

Working Principle of the 4N28SVM

The 4N28SVM optoisolator is a type of optoelectronic component used to provide electrical isolation between two circuits. It consists of an infrared light-emitting diode (LED) connected to a single transistor. The LED emits an infrared light which is detected by the transistor. When light is received, the transistor conducts, thus providing an isolated signal to the output side.

The 4N28SVM optoisolator is specially designed for high-speed motor control applications. It offers a wide bandwidth of up to 2 MHz and provides the reliable and isolated signal needed for motor speed control. The device also utilizes an internal noise suppression circuit, which reduces electrical noise between the input and output sides.

The 4N28SVM optoisolator is also designed for temperature sensing and relaying applications. It is capable of sensing temperatures up to 70°C with a resolution of 0.1°C. The device also offers high impedance isolation, allowing for reliable signal transmission in noisy environments.

The 4N28SVM optoisolator is an ideal choice for high-speed motor control and temperature monitoring applications. It offers excellent electrical isolation, high speed performance, and reliable signal transmission. With its high resolution temperature sensing capabilities, it is capable of providing excellent performance in any application.
