ABSTRACT:
According to one embodiment, there is provided an optocoupler system configured to generate current signals having high, low and no amplitude portions in response to the receipt of logic high and low input signals. The varying amplitude portions of the current signals are used to drive other portions of the isolation circuitry, and result in reduced power consumption and dissipation, as well as reduced pulse width distortion.
