PS2801A-1-F3-A Application Field and Working Principle

Optoisolators, or Optocouplers, are a type of electronic device which utilizes a short-distance optical path to provide electrical isolation between two systems. This allows for data to be relayed while Electrical Over Stress (EOS) and Electrostatic Discharge (ESD) protection are reliably maintained. The PS2801A-1-F3-A from Broadcom is an optoisolator which is capable of transmitting current in both directions, allowing for more flexibility in a wide variety of applications. This article briefly outlines the application field and working principle of the PS2801A-1-F3-A.The PS2801A-1-F3-A is a transistor, photovoltaic output optoisolator which is designed for use as an isolation interface between digital circuits and other complementary components. This makes it a suitable option for applications such as motor speed control, power supply isolation, modem isolation, and protection circuits. In addition to these, it is also useful in AD, DA input systems, and in analog signal transmission.The optoisolator\'s working principle is based on the electrical isolation provided by the photovoltaic effect. When light is shone onto the chip\'s photodiode, a single photon of light is absorbed and converted into an electron-hole pair. Further, when the LED is activated, current is generated through the photodiode, which is conditioned and processed by the chip\'s internal signal amplifier to produce a logic-level output.The key features of the PS2801A-1-F3-A which make it suitable for use in different applications include its wide operating temperature range of -40°C - 85°C, its low propagation delay of 500ns, and its high output current capability of up to 5mA. Other helpful features include its excellent ESD protection, a high-current common-mode interrupt capability of up to 0.2mA, and its low power dissipation of just 0.5mW.The PS2801A-1-F3-A is RoHS compliant and meets the standard requirements for safety agencies such as UL, VDE, TUV, and ENEC. Furthermore, it also offers a high level of EMI/bEMF Immunity.In conclusion, the PS2801A-1-F3-A is a transistor, photovoltaic output optoisolator which is designed for use in a variety of applications, such as motor speed control, power supply isolation, modem isolation, and protection circuits. Its working principle is based on the electrical isolation provided by the photovoltaic effect, and it has various helpful features, including a wide operating temperature range, a low propagation delay, and a high output current capability.
