Optoisolators, also known as optically-isolated amplifiers, are devices that are used to drive current between two or more electrically isolated circuits using a light source, typically an LED. The HCPL0730R2 is an optoisolator in the Optoisolator - Transistor, Photovoltaic Output category. It is a high-speed, digital optoisolator featuring a high speed, open-collector output with an active low logic input.

Features

The HCPL0730R2 features a high-speed 8-pin DIP package, a high peak pulse current of up to 150mA and a high operating temperature range of up to 105°C. It is also rated for an output current of up to 2.0A with very short rise and fall times. The device is also EMI immune and has a low power consumption of less than 50mW. It also features an open-collector output and can be used with any logic family from low speed to high speed logic systems. It is also RoHS compliant.

Applications

The HCPL0730R2 is a versatile optoisolator with a wide range of applications. The device is particularly suited for applications where high-speed digital data is present, such as in automotive and household appliances. It is also suitable for use in medical equipment, LEDs, safety systems and automation equipment.

Working Principle

The working principle of the HCPL0730R2 is to take a logic input and convert it into an open-collector output. When the logic input is in a high state (logic ‘1’), the LED inside the optoisolator will be illuminated and this will cause the output transistor to switch on. This will drive current to the output. When the input is in a low state (logic ‘0’), the LED will be off and the output transistor will be switched off, so no current is able to pass through the output.

The output is a non-inverting open-collector type, which will turn on in response to the input logic level. The output will remain on until the input is at a low logic level. It is designed to be used with an active pull-up resistor, which can vary depending on the particular application. The output has a limit of 2.0A, which allows it to be used for driving many different devices such as LEDs and relays.

Conclusion

The HCPL0730R2 is an optoisolator in the Optoisolator - Transistor, Photovoltaic Output category. It has a wide range of applications, including automotive and household appliances, medical equipment, LEDs, safety systems and automation equipment. It is an efficient, robust and reliable optoisolator with low power consumption and high speed response times. It is also EMI immune for use in high EMI environments.
