HCPL2531SM Application Field and Working Principle

Optoisolators - Transistor, Photovoltaic Output are typically used for isolation between a controller and signal, such as for industrial automation and control systems, for measurements, and for the control of motors and relays. The HCPL2531SM isolated transistor output is one such optoisolator designed to provide a high degree of isolation, and to seamlessly transfer control signals.

The HCPL2531SM optoisolator is based on the internal bridge configuration of the HCNW2531P optocoupler. Its patented HVIC technological core makes it the ideal solution for insulation applications where efficient heat dissipation is required to reduce operating temperature. It offers high-speed operation, high current flow capacity, and a high switching frequency. It also features metal film resistors, powder core, SMD pads, and wide operating temperature (-40°C to +85°C).

Working Principle

The HCPL2531SM optoisolator consists of an infrared LED and a high-speed MOSFET integrated in a single package between two pins. When the infrared LED transmits light, it excites a photovoltaic cell attached to the MOSFET, the current generated causes the MOSFET to turn on and off, thereby producing the transistor output.

The HCPL2531SM is designed to work with both AC and DC input signals. It has a wide operating power voltage of +/- 15V, an operating current up to 135mA, and a wide supply voltage range of 3.3V to 5.5V. The HCPL2531SM optoisolator has an isolation voltage of 3.75kVrms.
