HCPL-M700 Application Field and Working Principle

Optoisolator, also known as optocoupler, is an electronic device which uses a light source like a LED to transfer an electrical signal between two otherwise electrically isolated circuits. The HCPL-M700 is a type of optoisolator, particularly an optocoupler with transistor, photovoltaic output.

A pictorial representation of HCPL-M700 is given below:

The HCPL-M700 has a low voltage input section and a high power MOSFET output section to allow for complete galvanic isolation between two circuits. The input circuit consists of an infrared LED that emits light when an input signal is applied to it and a photo detector that generates an output when it is exposed to light. The output section is typically an integrated power MOSFET which is capable of switching higher power loads. The output is triggered by the photodetector in response to the light emitted by the LED. The HCPL-M700 optoisolator is available in a wide range of packages including single, dual, quad, and octal versions to meet the requirements of various applications.

The following illustration shows a simple circuit using the HCPL-M700 optoisolator:

The input section can be powered directly from a DC voltage source or from an AC source using a bridge rectifier. An input signal is applied to the control pin (pin 1) which causes the LED to emit light. This light is detected by the photodetector, triggering the output switch. The output voltage is applied to the load connected at the output pin (pin 2).

The HCPL-M700 transformer photovoltaic optoisolator has many applications in the electronics industry. It is often used to transfer signals between circuits operating at different voltages and galvanically isolate the two circuits from each other. This can be used to prevent noise or other interference on one circuit from corrupting the signal on another circuit. The HCPL-M700 optoisolator can also be used in power electronics applications to provide galvanic isolation between high voltage power sources and the control circuit.

The HCPL-M700 is a versatile optoisolator which can be used in many applications to provide isolation and signal control. It has a wide range of input and output voltages which makes it suitable for most applications. The output section can be used to switch large loads, allowing for remote control or automation of a variety of systems.
