Summary: | A circuit for supplying power to an intrinsically safe circuit having a power supply and output terminals includes an integrated current source feedback and current limiting element. Voltage limiting circuitry between the power supply and the output terminals limits the voltage across a load. Current limiting circuitry includes barrier resistors which convert current to voltage for input to an operational amplifier comparing a reference voltage with the voltage level representing the load current and providing a control input signal to a transistor for limiting a current applied to the load. |
