The CPC5002 is a dual high-speed digital optical isolator featuring open-drain outputs providing 3750 Vrms of galvanic isolation between the inputs and the outputs. It buffers two independent signals and supports 10 Mbaud typical data rates for digital communications over an optical barrier while providing 3750 Vrms of galvanic isolation.
The CPC5002 isolates two logic signals and is available in eight-pin surface mount or DIP packages. Utilizing a low-power, high-gain CMOS photodetector and requiring only 1.5 mA LED drive current, the CPC5002 is the industry's lowest power optical isolator or optocoupler. While most competitive devices work with a minimum supply of 3.0 V, the CPC5002 offers a higher degree of design flexibility with guaranteed operation as low as 2.7 V.
Unlike magnetically isolated digital isolator ICs, transformers, or capacitive isolators, the CPC5002 optical solution requires no internal clocking (a primary source of EMI/RFI interference in designs) and supports direct coupled logic-level isolation without refresh clocks. In addition, the unique design of the CPC5002 optical isolator offers excellent reliability and long operational life.
The CPC5002 Dual High-Speed Digital Optical Isolator is ideal for clock and data signals in isolated line receiver and bus receiver applications. The device may be used in Power-over-Ethernet (POE) applications, providing buffering and isolation of signals between the host controller and the Power Supply Equipment (PSE) controller. Additional applications include power supply high side interface and isolated signal monitoring and control. The wide operational power supply range specification of 2.7V to 5.5V enables logic-level translation applications. The CPC5002 is certified to UL 1577 and EN/IEC 60950.
