An isolation system and isolation device are disclosed. An illustrative isolation device is disclosed to include first circuitry having at least a first emitter and a first detector, second circuitry having at least a dual-purpose component, an isolation material configured to electrically isolate the first circuitry from the second circuitry, and switching circuitry adapted to connect the dual-purpose component to emit a first signal for detection by the first detector in a first configuration, and to receive a second signal from the first emitter in a second configuration.

Isolation device with half duplex channel

An optocoupler having optical lens layer is disclosed. The optocoupler may comprise an optical emitter, an optical receiver, an isolation layer, a lens layer and a substantially transparent encapsulant. The lens layer may be integrally formed within the optical receiver. Alternatively, the lens layer may be formed integrally with the isolation layer, or the lens layer may be an optical film attached on the optical receiver. The substantially transparent encapsulant may encapsulate at least partially the optical emitter, the optical receiver and the isolation layer. The isolation layer may be inserted to the substantially transparent encapsulant, making the substantially transparent encapsulant into two compartments. In another embodiment, an electronic system having optocoupler is disclosed.

Optocoupler having lens layer

An opto-isolator with a correction circuit is disclosed. The correction circuit is configured to make adjustments for degradation of the light source of the opto-isolator. The correction circuit may comprise a photodetector for detecting degradation of the light source of the opto-isolator. When the light source degrades below a predetermined level, the correction circuit may be configured to make adjustments.

Opto-isolator with correction circuit

An opto-isolator with a compensation circuit is disclosed. The compensation circuit may be configured to compensate degradation of the light source of the opto-isolator. The compensation circuit may comprise a circuit for counting an extended use of the isolator. When the count value exceeds a predetermined count value, the compensation circuit may be configured to compensate the degradation of the light source by adjusting the driver of the light source. In another embodiment, an electrical control system having such opto-isolator is illustrated.
