Optoisolators are used in a wide variety of applications to provide isolation. The CNY171VM photovoltaic output solid state opto-isolator is designed to provide a logic-level interface between circuits of widely different potentials. It features two pairs of emitter-detector elements which are optically coupled to provide voltage isolation and minimal current transfer. The CNY171VM acts as an analog switch with high isolation rated at 5 kV, giving it a wide range of application areas, from motor control and medical equipment, to measuring and controlling in industrial and aircraft applications. It is also used in industrial automation, robotics, photonics, and communication systems.

The CNY171VM consists of a detector and a logicgate integrated circuit that acts as a voltage regulator. The detector consists of two sets of paired LEDs and photodiodes, one side for the signal and the other side for confirmation. The signal LEDs are lighted when the signal is ‘high’ and the confirm LEDs are lighted when the signal is ‘low’. When the detector side receives a signal, either ‘high’ or ’low’, current will flow to the gates of the output transistors. The voltage at the gate determines the state of the output transistor, either ‘on’ or ‘off’.

The isolation between the input and the output of the CNY171VM is achieved through the use of optical coupling.Optical coupling works by using infrared LEDs to transmit the signal from one side of the device to another. The infrared light is converted to electrical current by a photodiode, which in turn is converted to digital logic. This type of optical isolation provides a physical barrier that prevents unwanted noise, as well as electrical isolation between two circuits.

The output signal from the CNY171VM is suitable for logic circuits, providing both low and high level signals. The device also allows for common-mode rejection up to 70 dB, ensuring signal fidelity and excellent noise immunity between the input and output circuits. Additionally, the CNY171VM has a wide range of bipolar input voltage, making it suitable for many different types of logic circuits.

The CNY171VM’s has a wide range of working temperature, from -40°C to 125°C. This makes it suitable for extreme temperature situations, such as in aviation, automotive, and military applications. The device is also able to withstand high voltage levels up to 35 V making it suitable for DC/DC conversion and inverter applications.

The CNY171VM is a useful tool for many designers as it can provide the isolation needed to interface between two circuits. Its small size and wide operating voltage range make it suitable for a wide range of applications. The optical isolation provided by the CNY171VM ensures that signals are free from unwanted noise and interference from the surroundings.
