The HCPL4502SDV optoisolator is a digital isolator component that combines a 6-pin optocoupler chip and a 10kV/µs photovoltaic (PV) transistor output with input/output isolation. Optoisolators, also called optical isolators, provide a high degree of electrical isolation between two circuits by transmitting data or power between them using optical signals. Designed for use in communications, industrial automation, medical, industrial, and automotive applications, the HCPL4502SDV offers superior performance and protection for isolated board-level systems.

The HCPL4502SDV optoisolator is designed to provide efficient power transfer and high isolation levels in a compact package. It operates with a single-mode optical fiber and employs an efficient non-contact coupling mechanism that eliminates the need for a floating ground. The optoisolator can switch up to two full-wave AC loads and is available in both 6-pin DIP and 8-pin DIP package versions.

The HCPL4502SDV optoisolator uses an advanced 8-bit microprocessor as the driver for the PV output transistor. The PV output transistor is capable of driving up to 2A of current, allowing for increased efficiency in power transfer between devices. The optoisolator also has an integrated full-duty cycle protection circuit which ensures that the circuit remains safe from over-voltage/over-current conditions.

The input of the optoisolator is a high-efficiency, single-mode optical fiber with an unambiguous core. The signal is one-wavelength long with a peak wavelength of 850nm. The light pulse is generated by a dedicated LED in the optoisolator and is sent to the optocoupler chip. The optocoupler chip then converts the optical signal into an electrical signal, which is used to drive the PV output transistor.

The PV output transistor is a bipolar power device capable of driving up to two full-wave AC loads with a maximum current rating of 2A. The transistor is a two-terminal device that is triggered by the optocoupler chip and acts as a switch for the electrical load. The trigger voltage for the mid-point (trigger) current is between 0.2V and 0.6V. The optoisolator can be used to switch resistive and capacitive loads over a wide range of operating temperatures.

The HCPL4502SDV optoisolator is a reliable and efficient component that provides protection against electrical noise and reduces the possibility of system failure due to electrical overloads. The optoisolator is designed for use in a variety of applications, including communications, industrial automation, medical, industrial, and automotive applications. Its compact size, high efficiency, and superior protection make it an ideal choice for board-level isolation requirements.
