VO2223B

The VO2223B is a type of optoisolator from the Triac, SCR Output family. It is used mainly as an isolation device, where an output can be driven directly from an input circuit. While the input circuit is open and the output is not connected, the output is completely isolated from the input.

The VO2223B is a high-performance optoisolator generally used in applications involving high-speed switching, precision timing and the elimination of electrical transients. It is suitable for linear or switching power supplies, motor control, process control and audio applications. The device also has a low on-state resistance (R ON) of 85Ω.

The VO2223B’s output can drive two-wire thermistors or other two-wire electronically-switchable loads. The device also features both fast and slow control functions. Its fast control function allows for 0.5ms switching time, making it suitable for high-speed switching applications. The slow control function allows for 10ms switching time, which is suitable for precision timing and transiency elimination applications.

The VO2223B has a LED-driven optically coupled output, meaning there is no direct electrical connection between the input and the output. The input provides an isolated electrical signal to the output when voltage is applied to it. An optically-coupled device or optocoupler is an electronic component, which provides electrical isolation between two circuits. The LED driven output also means that the device can be used with a wide variety of control signals.

When voltage is applied to the input side of the optoisolator, the LED emits light, which is received by a phototransistor. This causes the phototransistor to turn on, which in turn turns on the output, thus providing an electrical connection between the input and the output. The control current on the input side of the device can be in the range of 0.1mA to 50mA, which gives the device a wide range of control applications.

The VO2223B is also available in a variety of packages, including narrow lead and surface mount options. It also offers high sensitivity, high isolation, low power consumption and low temperature coefficient.

In conclusion, the VO2223B is an ideal optoisolator for applications which require high-speed, precision timing and transiency elimination. Its LED-driven optically coupled output and high R ON make it suitable for a wide variety of applications. And the wide range of packages offered makes it easy to integrate into any system.
