Abstract
This disclosure is directed towards systems and methods that may prevent backpowering of a voltage source during a current monitoring operation. In a first example circuit, a switch may be used to mitigate an offset voltage of an operational amplifier. In a second and third example, a resistor may be used to generate an opposing voltage to the offset voltage to mitigate the offset voltage of the operational amplifier. Other examples are described that may mitigate sensing dead zones of some of the solutions and/or that may mitigate temperature variations changing an effectiveness of the mitigation.
