An embodiment of a galvanic isolator comprises a generally planar electrically insulating substrate comprising opposing first and second surfaces, the substrate comprising an electrically insulating, low dielectric loss material and having a transmitter coil disposed on the first surface and a receiving coil disposed on the second surface. A transmitter circuit is operably connected to the transmitter coil. The transmitter circuit comprises a first detector that detects a rising edge of an input signal; a first pulse generator that generates a plurality of first pulses upon detection of the rising edge; a second detector that detects a falling edge of the input signal; and a second pulse generator that generates a plurality of second pulses upon detection of the falling edge. A receiver circuit is operably connected to the second receiving coil. The receiver circuit generates a signal that is substantially similar to the input signal based on the first pulses and the second pulses.

    摘要: In an opto-isolator, common mode pulses that occur are compensated for by either adding current to the electrical-to-optical converter (EOC) drive current to compensate for a decrease in the EOC drive current caused by the occurrence of a common mode pulse or by pulling some of the drive current away from the EOC to compensate for an increase in the EOC drive current caused by the occurrence of a common mode pulse.

The channels can be configured for various combinations of input signal amplification, input signal summation, analog output driving, and AC impedance measurement. The integrated circuit has 2 digital serial input lines and 2 digital serial output lines, all designed for direct connection to optical couplers. Channel configuration, gain, and other parameters are externally controllable by a serial digital input signal. Up to 6 compatible devices can be serially connected in a chain.

    摘要: In an opto-isolator, a common mode pulse compensation circuit is provided that senses when a common mode pulse event occurs and that adds current to the LED drive current to compensate for a decrease in the LED drive current caused by the occurrence of the event. The common mode pulse compensation circuit is capable of operating effectively over a very wide range of common mode pulse slopes by automatically adjusting the amount of current that is added to the LED drive current based at least in part on the slope of the sensed common mode pulse. In addition, the common mode pulse compensation circuit is capable of being implemented with LEDs that operate at very low drive currents, which allows the power consumption requirements of the opto-isolator to be reduced.
