This device can also provide 8kV surge and 2kV surge, which are necessary for digital isolator in the industrial field.

The FODM2701BR1 is ideal for providing isolation between host processor and LCD or communication interface. It also works with data transmission line and control circuit. It is available in various packages. Its features make it suitable for applications that require high data transmission rate and low power consumption. The FODM2701BR1 digital isolator is UL approved, which provides an excellent environmental temperature range from -40℃ to +125℃.

Working Principle of FODM2701BR1

The FODM2701BR1 is a photovoltaic isolator that includes two pairs of p-type and n-type transistors. The photovoltaic isolator uses a light-emitting diode (LED) to drive a photodiode to regulate the voltage between the two transistors. The LED has two electrodes, one is the anode and the other is the cathode. When the LED is energized by the power supply, it will generate photons to illuminate the photoconductor, which will generate a current between the two electrodes of the photodiode. This is the basic working principle of the FODM2701BR1.

The FODM2701BR1 isolator module uses an isolation gate to transfer data between two devices at different potentials. When the LED is energized, the photodiode will emit electrons, which will cause a current to flow between the two transistors. This current will then transfer the digital signal across the isolation barrier. The advantages of this type of isolator module are that it can provide isolation up to 4kV ESD protection, and it has high-speed data transmission and low power consumption.

The FODM2701BR1 photovoltaic isolator module has many uses in industry. It can provide isolation between host processor and communication interface, and its high-speed data transmission and low power consumption make it suitable for use in data transmission and control circuits. The optoisolator is UL approved, so it can be used in a wide variety of industrial applications.
