Optoisolators - Transistor, Photovoltaic Output

Optoisolators are electronic devices that use light to create electrical isolation between two conductive parts. They are typically used to provide galvanic isolation between electronic circuits where a direct electrical connection between two circuits could cause undesired or dangerous interactions. The HCPL-673K is an optoisolator with a transistor, photovoltaic output.The HCPL-673K combines a gallium arsenide infrared (GaAIr) emitting diode (LED) and NPN silicon photosensitive transistor in a single, 8-pin dual-in-line package. The LED has a forward voltage of 1.2V. When light from the LED strikes the base of the transistor, it causes the transistor\'s collector voltage to change according to the light intensity, creating the transistor output signal. The output characteristics of the HCPL-673K are field-programmable. Additionally, the device contains internal reverse voltage protection and ESD protection.The photovoltaic output of the HCPL-673K makes it ideal for applications requiring high voltage insulation such as power supplies, industrial motor control, and other applications where electrical isolation is necessary. The flexibility of the device\'s field programmable output characteristics makes it ideal for a wide range of applications. For example, the device can be used to convert low voltage analog signals into 4-20mA current loops, or to convert low voltage AC signals to 24V DC signals. Furthermore, the voltage-free output makes it suitable for interfacing with digital controllers.The HCPL-673K optoisolator is an ideal alternative to traditional couplers, DC-DC converters, and other isolators for applications that require electrical isolation. The small package size, high insulation voltage, and wide range of output characteristics make the device an excellent choice for interfacing between low level analog or digital signals and high voltage circuits. Its integrated ESD protection further enhances its suitability for safety-critical applications.In summary, the HCPL-673K optoisolator with a transistor, photovoltaic output is an effective and economical solution for applications that require electrical isolation. The device\'s small package size and field programmable output characteristics make it a versatile choice for a wide range of applications. Additionally, its integrated ESD protection ensures safety for high voltage circuits.
