HCPL-2201#560 Application Field and Working Principle

Optoisolators - Logic Output: Isolation is becoming increasingly important in the modern world of electronic designs. Optoisolators are devices that provide electrical isolation between signals in a system. The HCPL-2201 is an optoisolator device manufactured by Hewlett Packard. This optoisolator contains a 6-pin DIP package, single channel, and logic output. This device is mostly found in a variety of automation, arcade gaming, medical diagnostics, factory automation and various telecommunications applications.

The HCPL-2201#560 is designed to drive digital logic circuits. It uses an infrared light emitting diode (LED), an optical resistor, detector pop-up component and an open collector output stage. The LED will be in series with supply voltage and the output of the photodetector will be connected to series and shunt resistors, finally connecting to logic-level output. The photodiode provides an electrical signal proportional to the input optical power.

This optoisolator operates within the voltage range of 5V to 15V, with 200mA forward current and positive LED bias voltage. It has a 400 mW pulse power dissipation capability and the collector and emitter voltage is between 20V. The operating temperature range of the device is -40°C to 85°C and it can be mounted either horizontally or vertically. Other features of this optoisolator are that it has an input to output isolation voltage of 5000V peak and a UL1577 approved optical input safety rating.

The working principle of the HCPL-2201#560 optoisolator device involves the conversion of an electrical signal into an optical signal by the LED, transferring the optical signal across the gap and finally converting the optical signal back to an electrical signal by the photodetector. The input signal will cause the LED to be biased and generate an optical signal, which will be received by the photodetector. The current output of the photodetector is an amplified version of the original input signal. The current received by the phototransistor is amplified and converted to a voltage. This voltage provides the logic output.

The HCPL-2201#560 optoisolator device is used in various applications where signals need to be isolated from each other. This device is also used in many applications where high-voltage signals need to be blocked, such as in industrial controllers, motor control and air conditioners. This device can also be used for fiber optic communication systems, where the output of the device will be in the form of a signal indicating presence of light.

In summary, the HCPL-2201#560 is a logic output optoisolator device manufactured by Hewlett-Packard and is used in a variety of applications. It has a voltage range of 5V to 15V and a pulse power dissipation of 400mW. The device can provide electrical isolation between signals and blocks high-voltage signals. The device operates at temperatures from -40°C to 85°C and the optical input safety rating is UL1577 approved.
